A dipeptide, “x”, on complete hydrolysis gives “y” and “z”; “y” on treatment with aqueous HNO$_2$, produces lactic acid. On the other hand, “z” on heating gives the following cyclic molecule.
Based on the information given, the dipeptide X is:
List-I (Amino Acid) | List-II (Nature of Amino Acid) |
---|---|
(A) Valine | (I) Basic amino acid |
(B) Glycine | (II) Neutral optically active amino acid |
(C) Lysine | (III) Acidic amino acid |
(D) Glutamic acid | (IV) Neutral optically inactive amino acid |
