WebThiols are much more acidic than alcohols, due to oxygen being more electronegative than sulfur. That is why cysteine's side chain is ionizable and serine is not. P.S.: Actually, … Web26 feb. 2024 · In contrast, buried basic groups are expected to have low pKa values. However, many studies in this regard show that the relationship between pKa and solvation is complex (30, 31). This is because of the presence of strong electrostatic interactions between the corresponding ionizable group and the rest of charges in the protein.
