d-pantothenic acid

D-Pantothenic acid (vitamin B5) is a water-soluble vitamin ubiquitously found in plants and animal tissues with an antioxidant property. D-Pantothenic acid is a component of coenzyme A (CoA) and a part of the vitamin B2 complex. D-Pantothenic acid is a growth factor and is essential for various metabolic functions, including the metabolism of carbohydrates, proteins, and fatty acids. This vitamin is also involved in the synthesis of cholesterol, lipids, neurotransmitters, steroid hormones, and hemoglobin.

D-Pantothenic acid hemicalcium salt (Calcium pantothenate), a kind of water soluble vitamin, can reduce the patulin content of the apple juice.

D-Panthenol (D-Pantothenyl alcohol) is an alcoholic analogue of D-pantothenic acid and cholinergic agent. D-Panthenol acts as a precursor of coenzyme A necessary for acetylation reactions and is involved in the synthesis of acetylcholine. Although the exact mechanism of the actions of D-Panthenol is unclear, it may enhance the effect of acetylcholine. D-Panthenol acts on the gastrointestinal tract and increases lower intestinal motility. It is also applied topically to the skin to relieve itching and to promote healing.

Pantethine (Pantomin) (Bis-pantethine) is a dimeric form of vitamin B5. Pantethine is less stable than pantothenic acid and tends to decompose over time if it is not kept refrigerated, so most vitamin B5 supplements are in the form of calcium pantothenate. It is available as a dietary supplement and is used to treat acne and improve the blood-cholesterol profile.
