Description1-Pyrroline-5-carboxylic acid, also known as delta(1)-pyrroline-5-carboxylate, belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. 1-Pyrroline-5-carboxylic acid is a very strong basic compound (based on its pKa). 1-Pyrroline-5-carboxylic acid exists in all living species, ranging from bacteria to humans. Within yeast, 1-pyrroline-5-carboxylic acid participates in a number of enzymatic reactions. In particular, 1-pyrroline-5-carboxylic acid can be converted into L-proline; which is catalyzed by the enzyme pyrroline-5-carboxylate reductase. In addition, ubiquinol-1 and 1-pyrroline-5-carboxylic acid can be biosynthesized from L-proline and ubiquinone-1; which is mediated by the enzyme proline dehydrogenase. In yeast, 1-pyrroline-5-carboxylic acid is involved in the metabolic pathway called the proline metabolism pathway. 1-Pyrroline-5-carboxylic acid is a potentially toxic compound.
