Helical structure of protein is stabilised by ?
Proteins are found to have two different types of secondary structures viz α− helix and β− pleated sheet structure. α− helix structure of protein is stabilised by (a) peptide bonds (b) van der Waals, forces (c) hydrogen bonds (d) dipole-dipole interactions
In fibrous proteins, polypeptide chains are held together by ........... . (a) van der Waals forces (b) disulphide linkage (c) electrostatic forces of attraction (d) hydrogen bonds
