A) \[-\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-NH-\]
B) \[-\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-O-\]
C) \[-\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-O-\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-\]
D) \[-NH-\]
Correct Answer: A
Solution :
Protein and peptides form by the addition of amino acids. \[N{{H}_{2}}-\underset{\begin{smallmatrix} | \\ H \end{smallmatrix}}{\overset{\begin{smallmatrix} R \\ | \end{smallmatrix}}{\mathop{C}}}\,-COOH+N{{H}_{2}}-\overset{\begin{smallmatrix} R \\ | \end{smallmatrix}}{\mathop{CH}}\,-COOH\] \[\xrightarrow[-{{H}_{2}}O]{{}}\underset{dipeptide}{\mathop{N{{H}_{2}}-\overset{\begin{smallmatrix} R \\ | \end{smallmatrix}}{\mathop{CH}}\,-CO-NH-\overset{\begin{smallmatrix} R \\ | \end{smallmatrix}}{\mathop{CH}}\,-COOH}}\,\] Hence, protein and peptides contain peptide linkage, ie, \[-\underset{\begin{smallmatrix} || \\ O \end{smallmatrix}}{\mathop{C}}\,-NH-\]You need to login to perform this action.
