Information
Molar mass: 767.54 g/mol
Properties
Coenzyme A is a nucleotide derivative, highly soluble in water but insoluble in alcohol, ether and acetone.
In the metabolic processes of living organisms, it is an acyl-carrier coenzyme involved in both anabolic and catabolic processes. Its best-known derivative is acetyl coenzyme A (acetyl CoA), which transports the acetyl group required in the citric acid cycle.
Occurrence and production
It occurs in all metabolically active cells. In the human body, it is synthesized from vitamin B, mainly in the liver.
