"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). ... " - Titrationskurve glycin mit naoh
