BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The helix is stabilized by hydrogen bonds between an amide hydrogen of one amino acid and a carbonyl oxygen four amino acids away.

Detailed explanation-2: -Secondary structure The most common types of secondary structures are the helix and the pleated sheet. Both structures are held in shape by hydrogen bonds, which form between the carbonyl O of one amino acid and the amino H of another.

Detailed explanation-3: --helices are formed and maintained by backbone interactions parallel to the primary axis of the helix. These interactions are hydrogen bonds between the carbonyl oxygen and amino nitrogen of the ith and i + 4th amino acids.

Detailed explanation-4: -The alpha-helix is a right-handed helical coil that is held together by hydrogen bonding between every fourth amino acid.
