Question

The main forces that stabilize the $$2o$$ and $$3o$$ structures of a protein are.               (A) Hydrogen bonds                      (B) Bisulphide linkages                   (C) Vanderwaals forces                (D) Electrostatic forces

$$2o$$ structure is mainly stabilized by H–bonding. Overall folding of $$2o$$ structure represents $$3o$$ structure.Thus  $$20$$ and $$30$$ structures are stabilized by                    $$1)$$ Bisulphide linkages (S$$ – $$S)                $$2)$$ Vanderwaals forces (between$$ alkyl $$groups)                $$3)$$ Electrostatic forces  (between$$ $$-COO$$– and $$-NH3+$$ $$)                $$4)$$ $$H-bonds$$ between $$-CO-$$ and $$-NH-$$ gps
