Fig. 1From: Advanced glycation endproducts, dityrosine and arginine transporter dysfunction in autism - a source of biomarkers for clinical diagnosisProtein glycation, oxidation, and nitration free adducts. Ionization status at physiological pH is shown. For related adduct residues of proteins, alpha-amino-NH3+ and terminal carboxylate –CO2− groups are moieties of as peptide bonds –NH–CO– with amino acid residues immediately before and after in the peptide backboneBack to article page
