Pantothenic acid is a constituent of two important coenzymes, CoA and ACP. Coenzyme A is found in all tissues and is one of the most important coenzymes for tissue metabolism.
Pantothenic acid is found in two enzymes, coenzyme A (CoA) and acyl carrier protein (ACP), which are involved in many reactions in carbohydrate, fat and protein metabolism.
Pantothenic acid is widely distributed in feedstuffs of animal and plant origin. Alfalfa hay, peanut meal, cane molasses, yeast, rice bran, green leafy plants, wheat bran, brewer's yeast, fish solubles and rice polishings are good sources of the vitamin for animals. Corn and soybean meal diets are apt to be low in pantothenic acid. Milling by-products, such as rice bran and wheat bran, are good sources, being two to three times higher than the respective grains.
