Answer» Correct Answer - D Amino acids contain amino `(-NH_(2))` and carboxyl `(-COOH)` functional groups. Depending upon the relative position of amino group with respect to carboxyl group, the amino acid can be classified as `alpha, beta, gamma ,delta` and so on. Only `alpha`-amino acids. `H_(2)N - CH (R ) - CO_(2) H`, are obtained on hydrolysis of proteins. They may contain other functional groups also. Compound (4) called proline is different from the other amino acids as it is `2^(@)` amine and also the amino `N` is part of a five - membered ring. |
