5-ox·o·pro·line (Glp),

A keto derivative of proline that is formed nonenzymatically from glutamate, glutamine, and γ-glutamylated peptides; it is also produced by the action of γ-glutamylcyclotransferase; elevated levels of 5-oxoproline are often associated with problems of glutamine or glutathione metabolism.
