Question

The primary structure of a protein is due to?

• A. Hydrogen bond
• B. Peptide bonds
• C. -S-S-linkages
• D. Ionic bonds

Answer 1

The correct option is B Peptide bonds

The primary structure of a protein refers to the sequence of amino acids in the polypeptide chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of neighbouring amino acid. The linear sequence of amino acids within a protein is considered the primary structure of the protein.

Hence the correct answer is (B)
