Phenylpyruvic acid derivatives
WebOct 31, 2024 · A notable feature of phenylpyruvic acid derivatives 4 is their tautomerism, allowing the compounds to exist in solution as a mixture of two isomers: the keto form and the enol form. Compounds 4 may exist in solution as 3-(2-nitrophenyl)pyruvic acid (A) and 2-hydroxy-3-(2-nitrophenyl)acrylic acid (B) derivatives (Scheme 3). WebJan 22, 2024 · Phenylalanine is converted to phenylpyruvic acid. In particular, excessive phenylalanine can be metabolized into phenylketones through, a transaminase pathway route involving glutamate. Metabolites of this transamination reaction include phenylacetate, phenylpyruvate and phenethylamine. Structure.
