Vedclass · Answer

(B) $1$. Hydrolysis of dipeptide $X$ yields two amino acids,$Y$ and $Z$. $2$. $Y$ reacts with aqueous $HNO_2$ to form lactic acid $(CH_3CH(OH)COOH)$. This indicates that $Y$ is alanine $(CH_3CH(NH_2)COOH)$. $3$. $Z$ on heating forms a cyclic molecule. The structure provided is $2,5-$diketopiperazine,which is formed by the dimerization of glycine $(NH_2CH_2COOH)$. Thus,$Z$ is glycine. $4$. Therefore,the dipeptide $X$ is $alanine-glycine$.

$A$ 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:
