BIOMOLECULES AND ENZYMES

Detailed explanation-1: -To reiterate, the primary structure of a protein is defined as the sequence of amino acids linked together to form a polypeptide chain. Each amino acid is linked to the next amino acid through peptide bonds created during the protein biosynthesis process.

Detailed explanation-2: -The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries. The largest group of amino acids have nonpolar side chains.

Detailed explanation-3: -The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.

Detailed explanation-4: -The amino acid sequence is known as the primary structure of the protein. Stretches of polypeptide chain that form helices and sheets constitute the protein’s secondary structure.
