NEET levelSingle correct optionDifficulty 1 of 3bm085

The alpha-helix secondary structure of a protein is stabilised by

Aglycosidic linkages
Bhydrogen bonds between the C=O and N-H groups of the backbone
Cpeptide bonds between distant residues
Dionic bonds between all side chains

Answer: B

In an alpha-helix the backbone

C = O

of one residue forms a hydrogen bond with the backbone

N - H

of a residue further along the same chain, holding the coil in shape.
