Vitamin B5
Vitamin B5 Uses, Dosage, Side Effects, Food Interaction and all others data.
Vitamin B5, also called pantothenate or vitamin B5 (a B vitamin), is a water-soluble vitamin discovered by Roger J. Williams in 1919. For many animals, pantothenic acid is an essential nutrient as it is required to synthesize coenzyme-A (CoA), as well as to synthesize and metabolize proteins, carbohydrates, and fats. Vitamin B5 is the amide between pantoic acid and β-alanine and commonly found as its alcohol analog, the provitamin panthenol, and as calcium pantothenate. Small quantities of pantothenic acid are found in nearly every food, with high amounts in whole-grain cereals, legumes, eggs, meat, royal jelly, avocado, and yogurt. Vitamin B5 is an ingredient in some hair and skin care products. Only the dextrorotatory (D) isomer of pantothenic acid possesses biological activity. while the levorotatory (L) form may antagonize the effects of the dextrorotatory isomer.
Vitamin B5 is used in the synthesis of coenzyme A (CoA). CoA is thought to act as a carrier molecule, allowing the entry of acyl groups into cells. This is of critical importance as these acyl groups are used as substrates in the tricarboxylic acid cycle to generate energy and in the synthesis of fatty acids, cholesterol, and acetylcholine. Additionally, CoA is part of acyl carrier protein (ACP), which is required in the synthesis of fatty acids in addition to CoAs use as a substrate.
Vitamin B5 in the form of CoA is also required for acylation and acetylation, which, for example, are involved in signal transduction and enzyme activation and deactivation, respectively.

Uses
Vitamin B5 is a vitamin B5 found in various nutritional supplements.
Studied for the treatment of many uses such as treatment of testicular torsion, diabetic ulceration, wound healing, acne, obesity, diabetic peripheral polyneuropathy. It has also been investigated for its hypolipidemic effects and as cholesterol lowering agent.
Vitamin B5 is also used to associated treatment for these conditions: Nutritional supplementation
How Vitamin B5 works
Vitamin B5 is incorporated into COENZYME A and protects cells against peroxidative damage by increasing the level of GLUTATHIONE.
Toxicity
No Tolerable Upper Level Intake (UL) has been established for the vitamin.
Food Interaction
No interactions found.Elimination Route
Dietary pantothenic acid is primarily in the form of CoA or ACP and must be converted into free pantothenic acid for absorption. CoA and ACP are hydrolyzed into 4'-phosphopantetheine which is then dephosphorylated into pantetheine and subsequently hydrolyzed again to free pantothenic acid by Pantetheinase in the intestinal lumen. Free pantothenic acid is absorbed into intestinal cells via a saturable, sodium-dependent active transport system with passive diffusion acting as a secondary pathway. As intake increases up to 10-fold absorption rate can decrease to as low as 10% due to transporter saturation.
