coenzyme A in Science
coenzyme A  
A coenzyme that consists of a nucleotide linked to pantothenic acid (part of the vitamin B complex), is present in all living cells, and functions as an acyl group carrier. Coenzyme A is necessary for fatty acid synthesis and oxidation, pyruvate oxidation, and other acetylation reactions. In cellular respiration, each of two acetyl groups derived from the original glucose molecule attaches itself to coenzyme A as acetyl coenzyme A and then enters the Krebs cycle.
