Aniline reacts with acyl chlorides such as acetyl chloride to give amides. Phenyl acetate is the ester of phenol and acetyl chloride. Hydrolysis of the resulting acetyl iodide regenerates hydroiodic acid and gives acetic acid. Citrate synthase catalyzes the condensation of oxaloacetate with acetyl CoA to form citrate. Diacetyl and acetyl propionyl are associated with bronchiolitis obliterans. It is mainly utilized by organisms in the form of acetyl coenzyme A. The introduction of an acetyl group into a molecule is called acetylation. The amino group bears either an acetyl or a glycolyl group. The compound consists of two acetylcholine molecules that are linked by their acetyl groups. The sodium biocarbonates inhibits the autodyolysis of acetyl groups as well as inhibiting glycosic bonds. This step is also inhibited by acetyl CoA. Acetyl and pyruvyl residues are added as non-carbohydrate decorations. This process continues until the entire chain is cleaved into acetyl CoA units. These sugars can also be modified by the addition of sulfates or acetyl groups. In a competing mechanism, proton abstraction is concerted with the attack of acetyl CoA.
