gamma-Glutamylarginine
gamma-Glutamylarginine is a dipeptide composed of gamma-glutamate and arginine, and is a proteolytic breakdown product of larger proteins. It belongs to the family of N-acyl-alpha amino acids and derivatives. These are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. gamma-Glutamylarginine 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.
Glutamylarginine
Glutamylarginine is a dipeptide composed of glutamate and arginine, and is a proteolytic breakdown product of larger proteins. It belongs to the family of N-acyl-alpha amino acids and derivatives.

Glutamylarginine 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.
Arginylglutamic acid
Arginylglutamic acid is a dipeptide composed of arginine and glutamic acid. It is an incomplete breakdown product of protein digestion or protein catabolism.

N2-gamma-L-Glutamyl-L-arginine
Constituent of Allium cepa (onion), Panax ginseng (ginseng). After intravenous administration of DTIC-Dome, the volume of distribution exceeds total body water content suggesting localization in some body tissue, probably the liver. Its disappearance from the plasma is biphasic with initial half-life of 19 minutes and a terminal half-life of 5 hours. 1 In a patient with renal and hepatic dysfunctions, the half-lives were lengthened to 55 minutes and 7.2 hours. 1 The average cumulative excretion of unchanged DTIC in the urine is 40\\% of the injected dose in 6 hours. 1 DTIC is subject to renal tubular secretion rather than glomerular filtration. At therapeutic concentrations DTIC is not appreciably bound to human plasma protein. N2-gamma-L-Glutamyl-L-arginine is found in garden onion, tea, and onion-family vegetables.
