the helical structure of protein is stabilised by 574021667

The helical structure of protein is stabilised by

A. dipeptide bonds

B. hydrogen bonds

C. ether bonds

D. peptide bonds

Answer : hydrogen bonds

Solution :
The helical structure of protein is stabilised by hydrogen bonds between amide group of the same peptide chain. These bonds are formed by $$ - NH - $$ group of one unit and oxygen of carbonyl group of the other unit. It takes 3.6 amino acid to complete one tum of the helix to enable. Such $$H$$ - bonding and a 13 memberring is formed by $$H$$ - bonding. This $$H$$ - bonding is responsible for holding helix in a position.
