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: -In the polypeptide chain, the main structure of a protein relates to the amino acid sequence. The primary structure is bound together by peptide bonds that are made during the phase of protein biosynthesis.

Detailed explanation-3: -Amino acids that are connected by a peptide bond are called a polypeptide chain. The polypeptide chain is composed of a sequence of amino acids dictated by the gene.

Detailed explanation-4: -A protein molecule is made from a long chain of these amino acids, each linked to its neighbor through a covalent peptide bond (Figure 3-1). Proteins are therefore also known as polypeptides.
