Question

Distinguish between primary and secondary structure of protein

Answer 1

Answer:

• The primary structure is the number and sequence of amino acids held together by peptide bonds in a polypeptide chain.

                          The primary structure of a protein only describes the order of amino acids in the chain but tells.us nothing of the shape of the chain.

• Folding, kinking, or even pleating of the protein chainmade  by the amino acids of the primary structure constitute the secondary structure of the protein molecule.
