1-Pyrroline-5-carboxylic acid

1-Pyrroline-5-carboxylic acid, also known as 1-pyrroline-5-carboxylate, delta-1-pyrroline-5-carboxylic acid, and P5C, is an imino acid. The stereoisomer (S)-1-pyrroline-5-carboxylate is a biosynthetic metabolite that is synthesized from proline by the enzyme pyrroline-5-carboxylate reductase and converted into the amino acid glutamate by the enzyme 1-pyrroline-5-carboxylate dehydrogenase.
