Detailed explanation-3: -Elastin is composed of hydrophobic and alanine-rich and lysine-rich -helical segments that alternate along the polypeptide chain. The hydrophobic segments are responsible for the elastic properties of the molecule. The alanine-rich and lysine-rich -helical segments form cross-links between adjacent molecules.
