CHOLESTEROL METABOLISM IN PANTOTHENIC ACID DEFICIENCY

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...

The metabolism of pantothenic acid.

The formulation of this pathway was based on: (a) the finding that cysteine supplies the sulfur-containing moiety of CoA (3,4); (b) the activities of pantetheine and pantothenylcysteine as growth factors for Acetobacter suboxydans (4-6) and Lactobacillus helveticus (7); (c) the presence of enzymes in these two organisms and also in Lactobacillus bulgur&s which decarboxylate pantothenylcysteine ...

The modification of choline deficiency by simultaneous pantothenic acid deficiency.

It was found recently (1) that feeding a cholesterol-rich diet to pantothenic acid-deficient rats did not result in the fatty livers and high levels of cholesterol in liver and serum seen in comparable animals maintained on a normal diet. Decrease in food intake appeared not to account for this phenomenon, since the food intake of the deficient group on a body weight basis was higher than that ...

The metabolism in vitro of cardiac muscle in pantothenic acid deficiency.

An important r81e for pantothenic acid in carbohydrate metabolism was suggested by studies in which pantothenic acid-deficient bacteria (1, 2) and liver (3) were observed to utilize pyruvate at rates much less than normal. The subsequent discovery of Lipmann and his colleagues that the coenzyme of acetylation (coenzyme A) (4) contained pantothenic acid (5) provided a stimulus for the reinvestig...
