(A) tripeptide $Asp-Glu-Lys$ is formed by three amino acids: Aspartic acid $(Asp)$,Glutamic acid $(Glu)$,and Lysine $(Lys)$.$1$. Each peptide bond contains one $>C=O$ group. In a tripeptide,there are $2$ peptide bonds,contributing $2$ $>C=O$ groups.$2$. Aspartic acid $(Asp)$ has one side chain carboxyl group $(-COOH)$,which contains one $>C=O$ group.$3$. Glutamic acid $(Glu)$ has one side chain carboxyl group $(-COOH)$,which contains one $>C=O$ group.$4$. The terminal carboxyl group $(-COOH)$ of the tripeptide also contains one $>C=O$ group.Total number of $>C=O$ groups = $2$ (peptide bonds) + $1$ (Asp side chain) + $1$ (Glu side chain) + $1$ (terminal carboxyl) = $5$.

The number of $>C=O$ groups present in a tripeptide $Asp-Glu-Lys$ is.......
