प्रश्न
Write one difference between α-helix and β-pleated structures of proteins.
Advertisements
उत्तर
| α -helix | β -pleated sheet |
| The α -helix results from coiling of the protein chain such that the peptide bonds making up the backbone are able to form hydrogen bonds between each other. | The β -pleated sheet is a layering of protein chains one on the top of another. |
