MCQ
The helical structure of protein is stabilised by
- ADepeptide bond
- ✓Hydrogen bond
- CEther bond
- DEster bond
✓
Answer
Correct option: B.
Hydrogen bond
b
The helical structure of proteins is stabilized by hydrogen bonds. In helical structure, the carbonyl oxygen atoms in $C = O$ points in one direction, towards the amide hydrogen atoms in $NH$ groups,$4$ residues away. Together these groups form a hydrogen bond, one of the main forces of secondary structure stabilization in proteins. Hydrogen bonds are shown by dashed lines.
