Vedclass · Answer

(B) The number of ionizable functional groups in an amino acid depends on its structure. An amino acid typically contains at least one amino group $(-NH_2)$ and one carboxyl group $(-COOH)$. During titration,these groups dissociate at specific $pH$ values. For a neutral amino acid,the carboxyl group and the amino group are the primary ionizable sites,resulting in $2$ dissociating groups. Acidic amino acids contain an additional carboxyl group in the side chain,while basic amino acids contain an additional amino group,leading to $3$ or more dissociating groups.
