Thus, (CH 3 CO) 2 O is called acetic anhydride. Mixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known. One or both acyl groups of an acid anhydride may also be derived from another type of organic acid, such as sulfonic acid or a phosphonic acid.ixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known.

Structure of coenzyme A (CoASH or CoA) consists of a Î²-mercaptoethylamine group linked to the vitamin pantothenic acid through an amide linkage. The acetyl group of acetyl-CoA is linked by a high energy thioester to the sulfhydryl portion of the Î²-mercaptoethylamine. It is this thioester bond that makes acetyl-CoA one of the high energy compounds. Hydrolysis of the thioester bond is highly exergonic (-31.5 kJ). Acetyl-CoA is produced during breakdown of carbohydrates through glycolysis as well as fatty acid oxidation and enters the citric acid cycle. Acetyl-CoA is also an important component in the biogenic synthesis of the neurotransmitter acetylcholine.
