Concept introduction: Protein is made up of one or more amino acids linked together to form a chain. The building blocks of the protein are called amino acids. The eight essential amino acids are phenylalanine, isoleucine, leucine, methionine, histidine, lysine, tryptophan, threonine, and valine. The linear sequence of amino acid residues that are interlinked by a covalent bond is called peptide bond.
