Leucylproline
Leucylproline is a dipeptide composed of leucine and proline. 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). A dipeptide found in urine (PMID: 3782411). This is a proteolytic breakdown product of larger proteins. [HMDB]
Isoleucylproline
Isoleucylproline is a dipeptide composed of isoleucine and proline. 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).
N,N,N-Trimethyl-L-alanyl-L-proline betaine
N,N,N-Trimethyl-L-alanyl-L-proline betaine (TMAP) belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. TMAP was previously an unknown potential plasma biomarker for glomerular filtration rate (GFR) but its structure has since been elucidated (PMID: 28706470). TMAP has also been identified as a potential plasma biomarker of reduced kidney function in early chronic kidney disease (CKD), end stage renal disease (ESRD), and hemodialytic clearance (PMID: 31048706).
