Where Cα is the α-carbon, N represents the amide nitrogen and C_o is the carbonyl carbon of amino acids in a peptide, the peptide backbone of a protein consists of the repeated sequence:

Question

Quizplus · Accepted Answer

The peptide backbone consists of repeated units of the sequence −N−C_α−C_o−, in which the amide nitrogen (N) is bonded to the α-carbon (Cα) of one amino acid, and the carbonyl carbon (C_o) is bonded to the α-carbon (Cα) of the next amino acid. Therefore, option C is the correct choice as it correctly represents the order of the amino acids in the peptide backbone.

Where Cα Is the α-Carbon, N Represents the Amide Nitrogen
