In
summary, The vitamin B5 is
readily available from diverse dietary sources, a fact which is underscored by
the difficulty encountered in attempting to induce pantothenate deficiency.
Although pantothenic acid deficiency has not been linked with any particular
disease, deficiency of the vitamin results in generalized malaise
clinically. The vitamin pantothenic acid is an integral part of the
acylation carriers, CoA and acyl carrier protein (ACP). CoA has a crucial
role in the synthesis and degradation of many molecules, including vitamins A,
D, cholesterol, steroids, heme A, fatty acids, carbohydrates, amino acids, and
proteins.The major dietary sources of pantothenic acid are egg yolk, liver, kidney,
broccoli, and milk. Substantial concentrations of pantothenic acid are also
found in chicken, beef, potatoes, and whole grains.There is no known toxicity
for pantothenic acid. Excess intake is excreted by the
kidneys.
