Pantothenic Acid

Pantothenic Acid

Pantothenic acid is appropriately named because the Greek wordpantothenmeans “from many places.” It is fairly stable, but it can be damaged by acids and alkalies.

Functions.Pantothenic acid is involved in metabolism of carbohydrates,fats, and proteins. It is also essential for the synthesis of the neurotransmitter acetylcholine and of steroid hormones.

Sources.Pantothenic acid is found extensively in foods, especially animalfoods such as meats, poultry, fish, and eggs. It is also found in whole-grain cere-als and legumes. In addition, it is thought to be synthesized by the body.

Requirements.There is no DRI for pantothenic acid, but the Food andNutrition Board has provided an estimated intake of 4 to 7 mg a day for normal adults (see Table 7-2).

Deficiency.Natural deficiencies are unknown. However, deficiencies havebeen produced experimentally. Signs include weakness, fatigue, and a burning sensation in the feet. Toxicity from excessive intake has not been confirmed.
