Metabolite Identification
Common NameAcetylphosphate
DescriptionAcetylphosphate or actyl phosphate is a compound involved in taurine and hypotaurine metabolism as well as pyruvate metabolism. It is generated from sulfoacetaldehyde, converted to acetyl-CoA and acetate via phosphate acetyltransferase (EC:2.3.1.8) and acetate kinase (EC:2.7.2.1) respectively. It is also an intermediate in pyruvate metabolism. It is generated from pyruvate and the formation is catalyzed by pyruvate oxidase (EC:1.2.3.3).
