Leucylleucine is a dipeptide composed of two leucine residues. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. Leu-Leu-OH, a Leu derivative, is a dipeptide.
