Vedclass · Answer

(C) The general structure of an $\alpha$-amino acid is $H_2N-CH(R)-COOH$.Evaluating the options:$A$. Tyrosine has $R = -CH_2-C_6H_4-OH(p)$,which is correct.$B$. Cysteine has $R = -CH_2-SH$,which is correct.$C$. Serine has $R = -CH_2-OH$. The structure given,$R = -CH_2-CH_2-S-CH_3$,corresponds to Methionine,not Serine. Thus,this is incorrectly matched.$D$. Asparagine has $R = -CH_2-CONH_2$,which is correct.

The general structure of $\alpha$-amino acid can be represented as shown below. Which amino acid is not correctly matched with the $R$ group given?
