C21H36N7O16P3S
coenzyme A co*en"zyme A` (k[-o]*[e^]n"z[imac]m [=a]`), (Biochem.) a coenzyme ({C21H36N7O16P3S}) that participates in the transfer of acetyl groups in biochemical reactions; -- abbreviated {CoA}. It contains adenosine, phosphate, pantothenic acid and cysteamine groups. The acetyl group to be transferred during biosynthesis is temporarily attached to the free sulhydryl of the cysteamine group to form a thioester, in which state it is called acetyl coenzyme A. The strength of a preparation of coenzyme A may be expressed by the Lippman unit; one milligram of CoA contains 413 Lippman units. [PJC]
