All proteins have a primary structure. fibrous and globular proteins have a secondary structure: a helix or pleated globular
proteins also have a tertiary structure due to interactions of amino acid side chains with water. most globular proteins, including
hemoglobin also have a quaternary structure. which of these structures is due to h bonding between amino acid chains?

The correct answer is secondary structure of proteins is formed by the hydrogen bonding between amino acid chains.

Explanation:

The secondary structure of protein is generally stabilized by peptides bond along with hydrogen bonding between hydrogen atom and an electronegative atom such as oxygen.

      The secondary structure both alpha helix and beta pleated sheet are stabilized by hydrogen bonding beside the presence of peptide bonds.

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )
