Common Name | Prolylglycine |
---|
Description | Prolylglycine is a dipeptide composed of proline and glycine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. It is found in urine (PMID: 3782411 ). |
