Pantothenic Acid

(chick antidermatitis factor), a vitamin of the B complex. Pantothenic acid is a dipeptide amide of β-alanine and pantoic acid. In animal and plant cells, it occurs as a constituent of coenzyme A, which is involved in the most important metabolic reactions. The daily human requirement for pantothenic acid is 5–10 mg; this is satisfied by maintaining a normal balanced diet, since this vitamin occurs in many foods of both animal and vegetable origin, including yeast, fish roe, beef liver, egg yolk, greens, milk, carrots, and cabbage. Pantothenic acid is also synthesized by intestinal flora.

Pantothenic acid deficiency gives rise to metabolic disorders that promote the development of dermatitis, depigmentation, hair loss, fur and feather loss, and cessation of growth. Emaciation and changes in adrenal gland and nervous system activity arise, as well as disorders of motor coordination and of function in the liver, stomach, heart, and intestine. Pantothenic acid is used to relieve intestinal atony following gastrointestinal surgery, and its calcium salt is recommended for other therapeutic purposes.

pantothenic acid

[¦pan·tə¦then·ik ′as·əd] (biochemistry) C₉H₁₇O₅N A member of the vitamin B complex that is essential for nutrition of some animal species. Also known as vitamin B₃.

pantothenic acid

[pan″to-then´ik] a vitamin of the B complex present in all living tissues, almost entirely in the form of a coenzyme A (CoA). (See also vitamin.) This coenzyme has many metabolic roles in the cell, and a lack of pantothenic acid can lead to depressed metabolism of both carbohydrates and fats. The daily requirement for this vitamin has not been established, and no definite deficiency syndrome has been recognized in humans, perhaps because of its wide occurrence in almost all foods. Intakes of 4 to 7 mg/day are safe and adequate for adults. Some symptoms attributed to deficiency of other B complex vitamins may be due to a lack of pantothenic acid.

pan·to·then·ic ac·id

(pan'tō-then'ik as'id), The β-alanine amide of pantoic acid. A growth substance widely distributed in plant and animal tissues, and essential for growth of a number of organisms; dietary deficiency causes dermatitis in chicks, and dermatitis and achromotrichia in rats; a precursor to coenzyme A.

(păn′tə-thĕn′ĭk)n. A yellow oily acid, C₉H₁₇NO₅, belonging to and found widely in plant and animal tissues.

pantothenic acid

An essential nutrient involved in nutrient metabolism. Pantothetic acid (vitamin B5) is present in dairy products, egg yolks, leafy greens, legumes, liver and whole grains; it has been used by some alternative healthcare providers to treat allergies, anxiety, colitis, depression, eczema, fatigue, hay fever, hypoglycaemia, urticaria and to stimulate weakened adrenal glands. The recommended daily requirement is 100 mg.

(pan'tŏ-then'ik as'id) The β-alanine amide of pantoic acid. A growth substance widely distributed in plant and animal tissues, and essential for growth of a number of organisms; deficiency in diet causes a dermatitis in chicks and rats and achromotrichia in the latter; a precursor to coenzyme A.

pantothenic acid

One of the B group of vitamins and a constituent of coenzyme A which has a central role in energy metabolism. Deficiency is rare.

pantothenic acid

vitamin B5

a water soluble organic acid (C9H17O5N) that is present in all animal tissues, especially the liver and kidney. Pantothenic acid forms part of coenzyme A which, when bonded to acetic acid, forms ACETYLCOENZYME A. The vitamin is present in almost all foods, especially fresh vegetables and meat, eggs and yeast. A deficiency causes nervous disorders with poor motor coordination.
