PANTOTHENIC ACID AND COENZYME A IN THE ORGANS OF RATS IN PANTOTHENIC ACID DEFICIENCY AND ITS RECOVERY

The Liberation of Pantothenic Acid from Coenzyme

It was reported previously that coenzyme A contained pantothenic acid bound in such a manner as to make it unavailable in microbiological tests (1). A liberation of p;alanine on acid hydrolysis indicated early the presence of pantothenic acid, which was confirmed by chick assay (2). While the chick assay for pantothenic acid and the p-alanine assay by the yeast growth test yielded equivalent am...

The effect of pantothenic acid deficiency on acetylation in rats.

The ability of normal and pantothenic acid-deficient rats to acetylate a foreign substance was compared by injection of p-aminobenzoic acid (PAB) and the subsequent measurement of the acetylated PAB excreted. Young male rats weighing around 100 gm. or mature rats averaging over 300 gm. were used in various experiments. Those selected for pantothenate deficiency were given a purified diet free o...

Cholesterol metabolism in pantothenic acid deficiency.

Pantothenic acid deficiency induced in human subjects.

Bean and Hodges (1) gave a preliminary report of four young men in whom clinical disorders and metabolic faults were induced by a "diet" devoid of pantothenic acid, with omega-methylpantothenic acid, a vitamin antagonist (Figure 1). It is proposed here to describe details of the experiments, results, and some interpretations. The background for using molecular antagonists (2, 3) in human nutrit...
