Acetyl phosphate
Acetylphosphate, also known as acetyl-p, belongs to the class of organic compounds known as acyl monophosphates. These are organic compounds containing a monophosphate linked to an acyl group. They have the general structure R-CO-P(O)(O)OH, R=H or organyl. Since acetylphosphate synthesis is known to depend on cholinesterase activity, pseudocholinesterase was assumed to participate to a small extent in acetylphosphate synthesis by cancerous serum. It is also an intermediate in pyruvate metabolism. Acetylphosphate is a drug. Acetylphosphate exists in all living organisms, ranging from bacteria to humans. Acetylphosphate can be converted into acetic acid; which is mediated by the enzyme acylphosphatase-1. It is generated from pyruvate and the formation is catalyzed by pyruvate oxidase (EC:1.2.3.3). In humans, acetylphosphate is involved in the metabolic disorder called the pyruvate dehydrogenase complex deficiency pathway. 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. Acetylphosphate or actyl phosphate is a compound involved in taurine and hypotaurine metabolism as well as pyruvate metabolism. Cancerous serum produced 37% less acetylphosphate than normal serum.
