화학적 성질

Calcium D-Pantothenate is white crystalline powder

역사

Pantothenic acid (PA), also known as vitamin B5, is essential to all forms of life. Its name is derived from the Greek word pantos that means “everywhere”, which is appropriate for this widely, distributed vitamin.

용도

D-(+)-Pantothenic acid calcium salt is a member of the B complex vitamins; essential vitamin for the biosynthesis of coenzyme A in mammalian cells. Occurs ubiquitously in all animal and plant tissue. The richest common source is liver, but jelly of the queen bee contains 6 times as much as liver. Rice bran and molasses are other good sources.

정의

Calcium pantothenate, also known as calcium D-pantothenate or calcium pantothenic acid, is a naturally occurring form of pantothenic acid, an essential vitamin found in various foods. Calcium pantothenate is generally recognized as safe (GRAS) in the United States and in Europe. The US FDA requires infant formulas have at least 300 micrograms (mcg) per 100 calories of prepared formula.

화학 반응

Pantothenic acid is a constituent of coenzyme A, which participates in numerous enzyme reactions. CoA was discovered as an essential cofactor for the acetylation of sulfanilamide in the liver and of choline in the brain.

Biological Functions

Calcium D-Pantothenate accelerates the wound healing process by increasing the number of migrating cells, their distance and hence their speed.  In addition, cell division is increased and the protein synthesis changed.   Hence, higher quantities of pantothenate are locally required to enhance wound healing.

일반 설명

The first suggestion for the existance of vitamin B₅ came from Carter et al. in 1930; although it was never characterized or isolated. This vitamin is synthesized by most green plants and microorganisms. Excellent sources of the vitamin are liver, egg yolk, whole grains, and fortified ready-to-eat cereals. However, as the original name implies, many foods contain sufficient pantothenic acid to supply dietary needs.
Chemically, pantothenic acid is considered to be aβ-alanine derivative of the asymmetric pantoic acid and thus shows asymmetry. Only the naturally occurring D(+)- stereoisomer (with R configuration) is biologically active and the L(-)-stereoisomer (with S configuration) is inactive. When its carboxylate functional group is attached through an amide linkage with β-mercaptoethylamine, it is known as pantetheine (also spelled pantotheine). The biologically active form of pantothenic acid, CoA, is formed when the terminal alcoholic function of pantetheine is attached to ADP 3'-phosphate.

Clinical Use

The only therapeutic indication for pantothenic acid is intreatment of a known or suspected deficiency of this vitamin.Because of the ubiquitous nature of pantothenic acid, deficiencystates of this vitamin are only seen experimentally byuse of synthetic diets devoid of the vitamin, by use of thevitamin antagonist, ω-methylpantothenic, or both. In a 1991review, Tahiliani and Beinlich described that the mostcommon symptoms associated with pantothenic acid deficiencywere headache, fatigue, and a sensation of weakness.Sleep disturbances and gastrointestinal disturbances, amongothers, were also noted. The most likely setting for pantothenicacid deficiency is in the setting of alcoholism wherea multiple vitamin deficiency exists confounding the exactrole of the pantothenic acid deficiency as compared to theother vitamins. Because a deficiency of a single B vitamin israre, pantothenic acid is commonly formulated in multivitaminor B-complex preparations.

Safety Profile

Moderately toxic by intraperitoneal, subcutaneous, and intravenous routes. Mildly toxic by ingestion. A vitamin. See also CALCIUM COMPOUNDS. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

The salt crystallises as needles from MeOH, EtOH or isoPrOH (with 0.5mol of isoPrOH). It is moderately hygroscopic. The S-benzylisothiuronium salt has m 151-152o (149o when crystallised from Me2CO).
