If the α helix in chain B is amphipathic in nature and the side which faces the exterior. Introduction: Proteins are defined as the building block of amino acids. When two or more amino acids are linked in a chain, a compound called peptide is formed in which the carboxyl group of each acid is joined to the amino group of the next forming a − CO − NH − bond, known as peptide bond. Large number of amino acids are linked through peptide bonds to form proteins. The α helix consists of a coiled polypeptide chain. In the secondary structure of proteins an alpha helix structure held together by hydrogen bonds. Molecules like fatty acids that consist of polar as well as non-polar parts are called amphipathic.
