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.
