Proline
Description
Proline, C5H9NO2, is an amino acid which occurs under physiological conditions mainly as the nonpolar form, Pro, with pKa1 = 1.99 pKa2 = 10.96. Proline is a substrate that supports both proline dehydrogenase pathway control state and the glutamate anaplerotic pathway control state. Proline is oxidized in the mitochondrial matrix by L-proline:quinone oxidoreductase (Proline dehydrogenase, PDH) to delta-1-pyrroline-5-carboxylate. delta-1-pyrroline-5-carboxylate is converted to glutamate by 1-pyrroline-5-carboxylate dehydrogenase.
