Gamma-Glutamyltyrosine is made of glutamic acid and tyrosine. o-Tyrosine is a normal human metabolite. Its presence is possible due to the hydroxylation of l-phenylalanine by hydroxyl radical (*OH), and is proposed as an hydroxy radical biomarker of oxidative damage to proteins. o-Tyrosine might also be included in the diet and absorbed. It has been associated with disease such as Kwashiorkor, a severe form of protein-energy malnutrition. However, many publications mention that the results are inconclusive, and o-tyrosine is not selectively altered by antioxidant intervention, exercise training or age. (PMID: 14670743 , 10969271 , 9887186 ). N-gamma-L-Glutamyl-L-tyrosine is found in pulses. |
