Isoleucyl-Lysine

6-Amino-2-[(2-amino-1-hydroxy-3-methylpentylidene)amino]hexanoate

C12H25N3O3 (259.1896)


Isoleucyl-Lysine is a dipeptide composed of isoleucine and lysine. 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. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.

   

Lysylisoleucine

(2S,3S)-2-[(2S)-2,6-diaminohexanamido]-3-methylpentanoic acid

C12H25N3O3 (259.1896)


Lysylisoleucine is a dipeptide composed of lysine and isoleucine. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. 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.

   

Leucyl-Lysine

6-Amino-2-[(2-amino-1-hydroxy-4-methylpentylidene)amino]hexanoate

C12H25N3O3 (259.1896)


Leucyl-Lysine is a dipeptide composed of leucine and lysine. 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. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
