The “primary structure” of a protein refers to:
1. coiling due to hydrogen bonding between amino acids
2. the alpha helix or pleated sheets
3. the side groups of the amino acids
4. the number and sequence of amino acids

1. Primary structure
2. Secondary structure
3. Tertiary structure
4. Quaternary structure
