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...
متن کاملThe pantothenic acid content of coenzyme A by chick assay.
Lipmann, Kaplan, Novelli, Tuttle, and Guirard (1) reported that, whereas concentrates of the coenzyme required for acetylation (coenzyme A) showed no pantothenic acid activity by the ordinary microbiological assay, considerable amounts of p-alanine were found after acid hydrolysis. From this early observation, it was suspected that the coenzyme might contain combined pantothenic acid which was ...

PANTOTHENIC ACID – APPLICATIONS, SYNTHESIS AND BIOSYNTHESIS (Abstract): Pantothenic acid, also known as vitamin B5 or anti-stress vitamin, is a water-soluble vitamin with various applications in pharmaceutical industry (ointments, solut ions for treating lesions and irritation of the skin or mucous membranes, multivitamin supplements tablets, capsules, effervescent tablets, chewable tablets, sy...
متن کاملThe comparative activities of pantethine, pantothenic acid, and coenzyme A for various microorganisms.
Several fastidious lactic acid bacteria require a new growth factor, originally termed the Lactobacillus bulgartcu8 factor (LBF), for growth on synthetic media (Williams, Hoff-Jorgensen, and Snell, 1949; Kitay and Snell, 1950). Highly purified concentrates of this factor contained bound pantothenic acid, a finding that led to the discovery that LBF was apparently identical with the fragment of ...
