WebMar 30, 2024 · Using potentiometric titrations, UV-Vis, IR and speciation diagrams, it appeared that the simplest amino acid Glycine (Gly) is not reacting in a simple manner at all with the copper metal ion (Cu 2+) in aqueous solutions at 25˚C.The potentiometric measurements indicated that Cu 2+ released a net of two protons (2H + ’s) into the … WebApr 14, 2024 · In the case of Glycine,the R group does not contribute a dissociable Proton. The dissociation of proton proceeds in a certain order which depends on the acidity of the proton: the one which is most acidic and having a lower pKa will dissociate first. So, the H+ on the α-COOH group (pKa1) will dissociate before that on the α-NH3 group (pKa2). ...

At 50 % titration, the glycine exists as a zwitterion. This is the isoelectric point pI. At this point, pH=pI. For glycine, pKa1 = 2.34, pKa2 = 9.60, and pI = 5.97. Each amino acid has a characteristic set of pK and pI values.
