WebThe amino acid that contains a weakly acidic "phenolic" group is . tyrosine (Tyr, Y) ______are amino acids with neutral R groups containing an electronegative atom. Polar amino acids. The amino acid with the smallest-size side chain allowing greatest flexibility in a protein is . glycine. WebAt a pH lower than 2, both the carboxylate and amine functions are protonated, so the alanine molecule has a net positive charge. At a pH greater than 10, the amine exists as a neutral base and the carboxyl as its conjugate base, so the alanine molecule has a net negative charge.
