Acetyl 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 and acetate kinase respectively. It is also an intermediate in pyruvate metabolism.

Pneumadin, rat (PNM) is a decapeptide, which possess a potent stimulating effect on arginine-vasopressin (AVP) release. Pneumadin, rat (PNM) exerts a marked antidiuretic effect in animals with functional AVP system.

Phenylpyruvic acid is a keto-acid that is an intermediate or catabolic byproduct of phenylalanine metabolism. It has a slight honey-like odor. Levels of phenylpyruvate are normally very low in blood or urine. High levels of phenylpyruvic acid can be found in the urine of individuals with phenylketonuria (PKU) an inborn error of metabolism.
