Vedclass · Answer

(A) peptide bond is an amide linkage $(-CO-NH-)$ formed between the carboxyl group $(-COOH)$ of one amino acid and the amino group $(-NH_2)$ of another amino acid.Looking at the structure provided:$1$. The first linkage on the left is an amide bond $(-CH_3-CO-NH-)$,which is formed by the acetylation of an amino acid.$2$. The second linkage in the middle is a true peptide bond $(-CH(CH_3)-CO-NH-CH-)$ between two amino acid residues.$3$. The linkage on the right is a hydrazide group $(-CO-NH-NH_2)$,not a peptide bond.Therefore,there is only $1$ peptide bond in the given structure.The correct option is $A$.

The number of peptide bonds in the following compound is:
