What is Tocopherol?

Tocopherols (or TCP) are a chic of actinic compounds of which abounding accept vitamin E activity. It is a alternation of amoebic compounds consisting of assorted methylated phenols. Because the vitamin action was aboriginal articular in 1936 from a comestible abundance agency in rats, it was accustomed the name "tocopherol" from the Greek words acceptation in sum "to backpack a pregnancy," with the catastrophe "-ol" blame its cachet as a actinic alcohol.
alpha-Tocopherol is the capital antecedent begin in supplements and in the European diet, area the capital comestible sources are olive and sunflower oils, while gamma-tocopherol is the a lot of accepted anatomy in the American diet due to a college assimilation of soybean and blah oil.,
Tocotrienols, which are accompanying compounds, aswell accept vitamin E activity. All of these assorted derivatives with vitamin action may accurately be referred to as "vitamin E." Tocopherols and tocotrienols are fat-soluble antioxidants but aswell assume to accept abounding added functions in the body.
Tocopherols, although beneath frequently known, aswell accord to the vitamin E family. Tocotrienols accept four accustomed 2' d-isomers (they accept a stereoisomeric carbon alone at the 2' ring-tail position). The four tocotrienols (in adjustment of abbreviating methylation: d-alpha, d-beta, d-gamma, and d-delta-tocotrienol) accept structures agnate to the four tocopherols, except with an unsaturated band in anniversary of the three isoprene units that anatomy the hydrocarbon tail, admitting tocopherols accept a saturated phytyl appendage (the phytyl appendage of tocopherols gives the achievability for 2 added stereoisomeric sites in these molecules that tocotrienols do not have). Tocotrienol has been accountable to beneath analytic studies and apparent beneath analysis as compared to tocopherol. However, there is growing absorption in the bloom furnishings of these compounds.
Alpha-tocopherol is the form of vitamin E that is preferentially absorbed and accumulated in humans. The measurement of "vitamin E" activity in international units (IU) was based on fertility enhancement by the prevention of miscarriages in pregnant rats relative to alpha-tocopherol.
Although the mono-methylated form ddd-gamma-tocopherol is the most prevalent form of vitamin E in oils, there is evidence that rats can methylate this form to the preferred alpha-tocopherol, since several generations of rats retained alpha-tocopherol tissue levels, even when fed only gamma-tocopherol through their lives.

What is Casein phosphopeptides(CPP)?

A Casein phosphopeptides composition is prepared containing less than 4% phenylalanine, tyrosine and tryptophan, greater than 8% and less than 20% serine, a ratio of Ca+Mg+P/NT greater than 0.2, wherein NT is the total nitrogen content times 6.38, and free amino acids of less than 3%. The composition is useful as an ailment for dietetic or therapeutic nutrition or as a medicament. Salts of the phosphopeptides may be formed from macroelements such as calcium and/or magnesium and/or from oligoelements such as iron, zinc and copper. The composition is produced by proteolytic enzyme hydrolysis of a casein-based material, and using ultrafiltration and aggregration with a bivalent cation salt to isolate the phosphopeptide composition.
Recaldent, with the technical name Casein phosphopeptides – amorphous calcium phosphate, or CPP-ACP, is a milk-derived product that strengthens and remineralizes teeth and helps prevent dental caries (tooth decay). Casein phosphopeptides (CPP) from the major protein of milk have the ability to stabilize calcium, phosphate and fluoride ions as water soluble amorphous complexes that provide bioavailable calcium, phosphate and fluoride ions to the tooth. These complexes of amorphous calcium phosphate and amorphous calcium fluoride phosphate stabilized by the CPP have been demonstrated in a range of laboratory, animal and short-term human clinical trials to repair (remineralise) early stages of tooth decay by replacing the calcium and phosphate ions lost due to decay. Three longer-term, randomized, controlled clinical trials (RCTs) have demonstrated the efficacy of CPP-ACP in slowing the progression of dental caries and in regressing (repairing) early stages of tooth decay. Another RCT showed that CPP and calcium carbonate in a toothpaste formulation, which would spontaneously form CPP-ACP in saliva, significantly reduced caries experience in children compared with a placebo toothpaste. A systematic review with meta-analysis by Yengopal and Mickenautsch concluded that “the results of the clinical in situ trials indicate a short-term remineralization effect of CPP-ACP. Additionally, the promising in vivo RCT results suggest a caries-preventing effect for long-term clinical CPP-ACP use”. Recaldent (CPP-ACP) can be delivered to the teeth by sugar-free gum (Trident XtraCare with Recaldent), professional tooth crème (GC's Tooth Mousse, MI Paste and MI Paste Plus) and dairy milk (Meiji Milk de Recaldent).

Uses of Calcium pyruvate


Calcium pyruvate is a nutritional supplement that combines naturally occurring pyruvic acid with calcium. While pyruvate is produced in the body and aids in the conversion of sugar and starches into energy, calcium pyruvate can help enhance the metabolism and speed up the creation of energy. Along with helping people feel more energized, using the supplement can also aid in weight loss when used in conjunction with a sensible diet and regular exercise.
Because calcium pyruvate helps in burning fat to create more fuel for the body to use, the supplement helps to reduce fat that is retained in the body. Thus, the supplement can minimize the amount of excess fat that is stored around the abdomen and other parts of the body. The additional energy that is generated helps the body to function more efficiently and comes in handy when exercising as part of an overall health improvement regimen. In an indirect manner, this also means that calcium pyruvate aids in mental as well as physical health, since emotional issues often have a physical origin.
Uses of Calcium pyruvate
Aging skin. Applying a 50% pyruvic acid skin peel once a week for 4 weeks seems to smooth skin, decrease fine wrinkles, and decrease dark spots associated with aging due to sun exposure.

What is Cholecalciferol?

Cholecalciferol is a form of vitamin D, also called vitamin D3 or calcitriol.
It is structurally similar to steroids such as testosterone, cholesterol, and cortisol (though vitamin D3 itself is a secosteroid).
Forms
Vitamin D3 has several forms:
Cholecalciferol, (sometimes called calciol) is an inactive, unhydroxylated form of vitamin D3)
Calcifediol (also called calcidiol, hydroxycholecalciferol, 25-hydroxyvitamin D3, etc. and abbreviated 25(OH)D is one of the forms measured in the blood to assess vitamin D status
Calcitriol (also called 1,25-dihydroxyvitamin D3) is the active form of D3.
Cholecalciferol is synthesized in the skin from 7-dehydrocholesterol under the action of ultraviolet B light. It reaches an equilibrium after several minutes depending on several factors including conditions of sunlight (latitude, season, cloud cover, altitude), age of skin, and color of skin.
Although Cholecalciferol can be synthesized in the skin (see Metabolism), it is also a form of vitamin D added to fortify foods. Cholecalciferol is produced industrially by the irradiation of 7-dehydrocholesterol extracted from lanolin found in sheep's wool. In foods where animal products are not desired, an alternative compound is ergocalciferol (also known as vitamin D2) derived from the fungal sterol ergosterol.

Are you looking for Protein Phosphatase, beta PPP3R2 Monoclonal Antibody 5D9?


Protein phosphatases are a group of enzymes, found ubiquitously, which are responsible for the dephosphorylation of various proteins and enzymes in a cell. This role is an extremely important one since protein phosphorylation and dephosphorylation is required for the regulation of a large number of cellular activities.
Protein phosphatases were first reported to be inhibited by microcystins by Mackintosh et. al. (1990). It was found that extremely low concentrations of microcystin-LR could strongly inhibit protein phosphatases 1 and 2A from both plants and mammals, thereby causing hyperphosphorylation of the cell and a massive disruption of a number of important cellular mechanisms.
The binding of microcystins to protein phosphatases is covalent and therefore very inhibitory and highly specific. The processes involved in the binding of microcystins to protein phosphatases is the subject of some research.
Calcineurin subunit B type 2 is a protein that in humans is encoded by the PPP3R2 gene.
Protein phosphatase 2 (PP2), also known as PP2A, is an enzyme that in humans is encoded by the PPP2CA gene. The PP2A heterotrimeric protein phosphatase, is a ubiquitous and conserved Serine/Threonine phosphatase with broad substrate specificity and diverse cellular functions. Among the targets of PP2A are proteins of oncogenic signaling cascades, such as Raf, MEK, and AKT.

What is Ergocalciferol?

Ergocalciferol is a form of vitamin D, also called vitamin D2. It is marketed under various names including Deltalin (Eli Lilly and Company), Drisdol (Sanofi-Synthelabo) and Calcidol (Patrin Pharma). Created from viosterol when ultraviolet light activates ergosterol (found in fungi, it is named as a sterol from ergot), with fungi as the primary plant source.
Ergocalciferol may be used as a vitamin D supplement, and a 2011 clinical guideline considered it to be as effective as cholecalciferol (vitamin D3), which is produced naturally by the skin when exposed to ultraviolet light. Conflicting evidence exists for how similarly D2 and D3 behave in the body and whether they are equally active, with some studies suggesting D3 is more potent, while others report equal efficacy. Cholecalciferol (vitamin D3) is sensitive to UV radiation and rapidly, but reversibly, forms other sterols which can further irreversibly convert to ergosterol.
Ergocalciferol is produced in fungus synthetically from radiating an ergosterol. Human bioavailability of vitamin D2 from vitamin D2-enhanced button mushrooms via UV-B irradiation is effective in improving vitamin D status and not different to a vitamin D2 supplement. Vitamin D2 from UV-irradiated yeast baked into bread is bioavailable. By visual assessment or using a chromometer, no significant discoloration of irradiated mushrooms, as measured by the degree of "whiteness", was observed. Claims have been made that a normal serving (approx. 3 oz or 1/2 cup, or 60 grams) of mushrooms treated with ultraviolet light provides vitamin D content to levels of 3,476 IU if exposed to just 5 minutes of UV light after being harvested.

Since then, it has been shown to be involved in the regulation of a diverse array of cellular functions, including protein synthesis, cell proliferation, cell differentiation, microtubule assembly/disassembly, and apoptosis. GSK3s substrate specificity is unique in that phosphorylation of substrate only occurs if a phosphoserine or phosphotyrosine is present four residues C terminal to the site of GSK phosphorylation. There exists two isoforms of GSK3, alpha and beta, and they show a high degree of amino acid homology. The two isoforms of GSK3 are strictly regulated via phosphorylation. Phosphorylation of GSK3 beta on Ser9 (Ser21 in GSK3 alpha) by protein kinase B (PKB) causes its inactivation is the primary mechanism responsible for growth factor inhibition of this kinase. Activation of GSK3 beta is dependent upon the phosphorylation of Tyr216 (Tyr279 in GSK3 alpha). Upon activation, it has been shown to phosphorylate a number of different cellular proteins, including p53, c-Myc, c-Jun, heat shock factor 1 (HSF1), and cyclin D1. GSK3 beta also has been shown to phosphorylate aberrant sites on the microtubule associated protein tau, which is critical for the progression of Alzheimer's disease. GSK3B is involved in energy metabolism, neuronal cell development, and body pattern formation.

Properties of Histidine

Histidine (abbreviated as His or H) Histidine, an capital amino acid, has a absolutely answerable imidazole anatomic group. It is one of the 22 proteinogenic amino acids. Its codons are CAU and CAC. Histidine was aboriginal abandoned by German physician Albrecht Kossel in 1896. Histidine is an capital amino acerbic in bodies and added mammals. It was initially anticipation that it was alone capital for infants, but longer-term studies accustomed that it is aswell capital for developed humans.
Properties
The imidazole sidechain of histidine has a pKa of about 6.0, and, overall, the amino acerbic has a pKa of 6.5. This agency that, at physiologically accordant pH values, almost baby accouterment in pH will change its boilerplate charge. Below a pH of 6, the imidazole ring is mostly protonated as declared by the Henderson–Hasselbalch equation. When protonated, the imidazole ring bears two NH bonds and has a absolute charge. The absolute allegation is appropriately broadcast amid both nitrogens and can be represented with two appropriately important resonance structures.
Aromaticity
The imidazole ring of histidine is ambrosial at all pH values. It contains six pi electrons: four from two bifold bonds and two from a nitrogen abandoned pair. It can anatomy pi stacking interactions, but is complicated by the absolute charge. It does not blot at 280 nm in either state, but does in the lower UV ambit added than some amino acids.
Biochemistry
The imidazole sidechain of Histidine is a accepted analogous ligand in metalloproteins and is a allotment of catalytic sites in assertive enzymes. In catalytic triads, the basal nitrogen of histidine is acclimated to abstruse a proton from serine, threonine, or cysteine to actuate it as a nucleophile. In a histidine proton shuttle, histidine is acclimated to bound shuttle protons, it can do this by abstracting a proton with its basal nitrogen to accomplish a positively-charged average and again use addition molecule, a buffer, to abstract the proton from its acerb nitrogen. In carbonic anhydrases, a histidine proton shuttle is activated to rapidly shuttle protons abroad from a zinc-bound baptize atom to bound change the alive anatomy of the enzyme.
As expected, the 15N actinic accouterment of these nitrogens are duplicate (about 200 ppm, about to nitric acerbic on the sigma scale, on which added careful corresponds to added actinic shift). As the pH increases to about 8, the protonation of the imidazole ring is lost. The actual proton of the now-neutral imidazole can abide on either nitrogen, giving acceleration to what is accepted as the N-1 or N-3 tautomers. NMR shows that the actinic about-face of N-1 drops slightly, admitting the actinic about-face of N-3 drops appreciably (about 190 vs. 145 ppm). This indicates that the N-1-H tautomer is preferred, it is accepted due to hydrogen bonding to the adjoining ammonium. The careful at N-3 is essentially bargain due to the second-order paramagnetic effect, which involves a symmetry-allowed alternation amid the nitrogen abandoned brace and the aflame pi* states of the ambrosial ring. As the pH rises aloft 9, the actinic accouterment of N-1 and N-3 become about 185 and 170 ppm. It is account acquainted that the deprotonated anatomy of imidazole, imidazolate ion, would be formed alone aloft a pH of 14, and is accordingly not physiologically relevant. This change in actinic accouterment can be explained by the apparently decreased hydrogen bonding of an amine over an ammonium ion, and the favorable hydrogen bonding amid a carboxylate and an NH. This should act to abatement the N-1-H tautomer preference.

Uses of Zinc Gluconate

Zinc Gluconate (also called zincum gluconicum) is the zinc salt of gluconic acid. It is an ionic compound consisting of two moles of gluconate for each mole of zinc. Zinc gluconate is a popular form for the delivery of zinc as a dietary supplement.
Gluconic acid is found naturally, and is industrially manufactured by the fermentation of glucose, typically by Aspergillus niger, but also by other fungi, e.g. Penicillium, or by bacteria, e.g. Acetobacter, Pseudomonas and Gluconobacter. In its pure form, it is a white to off-white powder. It can also be manufactured by electrolytic oxidation, although this is a more expensive process. The advantages are a lower microbiological profile, and a more complete reaction, yielding a product with a longer shelf life.
Zinc gluconate may interfere with the absorption of antibiotics, so combinations may be unsafe.
Zinc Gluconate contains not less than 97.0 percent and not more than 102.0 percent of C12H22O14Zn, calculated on the anhydrous basis.
Characteristic: Dehydrate compound, white or off-white crystal powder, be soluble easily in water, no odor and taste, hardly soluble in ethanol, chloroform and aether
Usage And Functions
An essential element for normal growth and good vision. Its benefit in maintaining healthy skin, bones, collagen and protein synthesis as well as proper sexual function and the immune system; help in the utilisation of vitamin A, Calcium and Phosphorous. A Zinc supplement may help to ensure against any deficit in the diet, especially during the winter months.

Where to get GSK-3 alpha/beta (phospho-Tyr216/Tyr279) Polyclonal Antibody?

Immunogen
Synthetic peptide (Human) (C terminal).
Storage instructions
Shipped at 4°C. Upon delivery aliquot and store at -20°C. Avoid freeze / thaw cycles.
Primary antibody notes
GSK-3 (Glycogen Synthase Kinase-3 differs from most serine/threonine kinases) in that it is active in the absence of the action of signaling pathways. Two isoforms exist, GSK-3a and GSK-3ß. The function of GSK-3 is to phosphorylate glycogen synthase and thereby inactivate it. Insulin action stimulates the PI 3-kinase pathway, resulting in Akt activation, which phosphorylates and inactivates GSK-3.
Glycogen synthase kinase 3 (GSK3) is a proline directed serine threonine kinase that was initially identified as a phosphorylating and inactivating glycogen synthase, a key enzyme in glycogen metabolism. Since then, it has been shown to be involved in the regulation of a diverse array of cellular functions, including protein synthesis, cell proliferation, cell differentiation, microtubule assembly/disassembly, and apoptosis. GSK3s substrate specificity is unique in that phosphorylation of substrate only occurs if a phosphoserine or phosphotyrosine is present four residues C terminal to the site of GSK phosphorylation. There exists two isoforms of GSK3, alpha and beta, and they show a high degree of amino acid homology. The two isoforms of GSK3 are strictly regulated via phosphorylation. Phosphorylation of GSK3 beta on Ser9 (Ser21 in GSK3 alpha) by protein kinase B (PKB) causes its inactivation is the primary mechanism responsible for growth factor inhibition of this kinase. Activation of GSK3 beta is dependent upon the phosphorylation of Tyr216 (Tyr279 in GSK3 alpha). Upon activation, it has been shown to phosphorylate a number of different cellular proteins, including p53, c-Myc, c-Jun, heat shock factor 1 (HSF1), and cyclin D1. GSK3 beta also has been shown to phosphorylate aberrant sites on the microtubule associated protein tau, which is critical for the progression of Alzheimer's disease. GSK3B is involved in energy metabolism, neuronal cell development, and body pattern formation.
