Gamma-Glutamylmethionine
gamma-Glutamylmethionine is a dipeptide composed of gamma-glutamate and methionine, 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-Glutamylmethionine 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. gamma-Glutamylmethionine is found in onion-family vegetables. It is isolated from the seeds of onion (Allium cepa), kidney bean (Phaseolus vulgaris), mung bean (Vigna radiata), garlic (Allium sativum), and black gram (Vigna mungo).
Glutamylmethionine
Glutamylmethionine is a dipeptide composed of glutamate and methionine, 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. Glutamylmethionine 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.
Methionyl-Glutamate
Methionyl-Glutamate is a dipeptide composed of methionine and glutamate. 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.
