State differences between α-helix and β-pleated sheet structure.
| α-helix structure | β-pleated structure |
| 1. In α-helix. the peptide chains are coiled upto form helix which is right handed involving hydrogen bonding. | 1.The peptide chains lie side by side held together by inter molecular hydrogen bonding. |
| 2. Myosin, keratin and wool have α-helix structure. It acquires coil shape. |
