Description: Coenzyme A is an essential cofactor in enzymatic acetyl transfer reactions. The principal biologically active forms of pantothenic acid are coenzyme A (CoA) and acyl carrier protein (ACP). In CoA, the business center of the molecule is the pantothenic acid metabolite 4'-phosphopantetheine. Coenzyme A is comprised of 4'-phosphopantetheine linked by an anhydride bond to the nucloetide adenosine 5'-monophosphate. 4'-Phosphopantetheine itself is comprised of pantothenic acid linked at one end, via an amide bond, to beta-mercaptoethylamine, derived from L-cysteine, and at the other end to a phosphate group. The sulfhydryl group of 4'-phosphopantetheine, which is the business end of the coenzyme, forms thioesters with acyl groups producing acyl-CoA derivatives, including acetyl-CoA.
Coenzyme A facilitates removal of lipid peroxides by increasing mobilization of fatty acids, and promote repair of plasma membranes by activating phospholipid synthesis.

Description: Folic acid, also known as folate, is a B vitamin that can be found in a variety of fruits and vegetables. It can also be chemically synthesized. Folate, a watersoluble vitamin, helps the body form red blood cells and aids in the formation of genetic material within every body cell. This product exhibits metal binding properties. Hematopoietic vitamin present, free or combined with one or more additional molecules of L-(+)-glutamic acid, in liver, kidney, mushrooms, spinach, yeast, green leaves, and grasses.
Folic acid (Vitamin B9 and folate) is essential to numerous bodily functions. The human body needs folate to synthesize DNA, repair DNA, and methylate DNA as well as to act as a cofactor in certain biological reactions. It is especially important in aiding rapid cell division and growth, such as in infancy and pregnancy.
Folic acid (FA) and dihydrofolic acid (FAH2) are substrates of dihydrofolate reductase(s) which reduce them to tetrahydrofolate (THF), which in turn supports ‘one carbon’ transfer. Tetrahydrofolates are required for de novo synthesis of purines, thymidylic acid and various amino acids and for post-translational methylation (epigenetics).
Very slightly soluble in cold water (0.0016 mg/mL at 25 °C), soluble to about 1% in boiling water. Slightly soluble in methanol, appreciably less soluble in ethanol and butanol. Insoluble in acetone, chloroform, ether, benzene. Relatively soluble in acetic acid, phenol, pyridine, solutions of alkali hydroxides and carbonates. Soluble in hot dilute HCl and H2SO4.

Catalog Number: (IC10205680)
Supplier: MP Biomedicals
Description: Preparation Method: MP Intrinsic Factor is produced from the pylorus mucous membrane of the pig, of which only a small part is used. Only the part which, according to histological examinations has proved to have a high content of Intrinsic Factor, is used.
Applications: Intrinsic Factor is used in the treatment not only of classical pernicious anaemia, but also in the treatment of other macrocytic anaemias, where it replaces the Intrinsic Factor which may be lacking in the patient's own gastric juice. In this way Intrinsic Factor is recommended against anaemias that appear 6 to 12 months after serious gastric operations, and against anaemias that are secondary effects of the treatment with certain medicines, e.g. against epilepsy. However, the dietetic use in multi-vitamin preparations is of the greatest importance. In older people there has been observed a degeneration of the gastric mucous membrane, whose secretion of Intrinsic Factor is insufficient to ensure the resorption of the necessary quantity of B-12 from their diet. In order to delay this development it is useful to prescribe a small quantity of Intrinsic Factor with B-12 and other vitamins to these patients.
Product Description: Intrinsic factor is a glucoprotein extracted from the pylorus part of the gastric mucous membrane. Its presence is considered necessary for the absorption of Vitamin B-12.
Unit Definition: The activity is normally indicated in Coli units, the number of which are proportional to the binding power of the substance to Vitamin B-12.

Application Areas: Absorption of vitamin B12
Product Type: Proteins, Enzymes & Peptides
Presentation: Tan Powder
Foreign activity: Salmonella=Negative, E. coli=Negative
NOTES: Standard Plate Count <1000/g
Solubility: Slightly soluble in toluene; practically insoluble in water.
