Arginylarginine
(2S)-2-[(2S)-2-amino-5-carbamimidamidopentanamido]-5-carbamimidamidopentanoic acid
Arginylarginine is a dipeptide composed of two arginine residues. 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.
