The sequence of amino acids held together by peptide bonds is the primary structure which is a linear sequence built by twenty one amino acids each having unique side chain.
The amino acids are small organic molecules consisting of central carbon atom linked to an amino group , a carboxyl group, a hydrogen atom and variable component. Within a protein, multiple amino acids linked together by peptide bond forming long chain. Peptide Bond are formed by a biochemical reaction extracting water molecules as it joins the amino group of one amino acid to the carboxyl group of neighboring amino acid.
The primary structure of protein drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's three dimensional shape.
Hence, the correct answer will be option (a)
