Question

which of the following is not a way in which amino acid structure in sequence might affect the properties of a protein

a) Amino acid side chains form peptide bonds with each other causing the molecule to twist into a secondary structure

b) Amino side chains interact with each other causing polypeptides to bend into a tertiary structure

c) Hydrogen bonding between every fourth amino acid results in the formation of a coil called an a helix

d) Hydrogen bonding between strands of parallel polypeptide chains cause 8 pleated sheets to form

Answer 1

The function of protein is directly dependent on its three-dimensional structure which is determined by the sequence of amino acids in a polymer.

a) Amino acid side chains form peptide bonds with each other causing the molecule to twist into a secondary structure

The above-mentioned option should be the answer because amino acid side chains form peptide bonds with each other to form the primary structure of a protein and not the secondary structure as stated in the option.

Rest all options are correct.
