Question

-C||ONH-(peptide bond) which statement is incorrect about peptide bond

• A. C–N bond length in protiens is longer than usual bond length of N-bond
• B. Spectroscopic analysis show planar structure of – C –NH –O group
• C. C–N bond length in proteins is smaller than usual bond length of C–N bond
• D. None of above

Answer 1

Answer: (A)

C–N bond length in protiens is longer than usual bond length of N-bond

Answer 2

The correct option is(A): C–N bond length in protiens is longer than usual bond length of N-bond. Peptide bonds are indeed the chemical bonds that connect two adjacent amino acids in a protein chain, leading to the formation of proteins. These bonds are formed through a condensation reaction (also known as dehydration synthesis) between the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another amino acid.
