Vedclass · Answer

(A) The general structure of an $\alpha$-amino acid is $NH_2-CH(R)-COOH$. In tryptophan,the $R$ group is an indolyl-methyl group (specifically,a $3$-indolylmethyl group). In histidine,the $R$ group is an imidazolyl-methyl group (specifically,a $4$-imidazolylmethyl group). Therefore,the correct representation for $R$ in tryptophan $(X)$ and histidine $(Y)$ is the indolyl-methyl group and the imidazolyl-methyl group respectively.

The general structural formula of $\alpha$-amino acid is $NH_2-CH(R)-COOH$. The group $R$ in tryptophan $(X)$ and histidine $(Y)$ are respectively:
