N-Glycyl-L-tyrosine

N-Glycyl-L-tyrosine (CAS No.: 658-79-7) is a synthetic dipeptide composed of glycine and L-tyrosine that serves as a representative small peptide model in studies of protein metabolism, peptide transport, and amino acid-derived signaling processes. As an intermediate or incomplete degradation product of protein catabolism, it is frequently utilized to investigate peptide absorption mechanisms and enzymatic hydrolysis in cellular and biochemical systems. Experimental evidence suggests that this dipeptide may influence specific enzymatic activities and modulate signaling pathways associated with amino acid sensing and metabolic regulation, although its precise molecular targets remain context-dependent and are typically characterized in vitro. Reported biological effects are generally observed within low micromolar to millimolar concentration ranges, consistent with its role as a low-molecular-weight peptide substrate or modulator in biochemical assays. N-Glycyl-L-tyrosine is widely applied in cell-based and enzymatic models to study peptide transporter function, protease specificity, and metabolic flux, as well as in broader investigations of signaling pathway modulation in disease-relevant experimental systems. The concentrations or doses employed vary according to specific experimental designs and research objectives, particularly in studies focused on peptide-mediated regulatory mechanisms and screening platforms for enzyme activity or transport kinetics.
