متن کاملThe 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...
