Expert Solution

Step 1

A protein's function depends on its structure. There are four levels of protein structure: primary, secondary, tertiary and quaternary.

The primary structure is the amino acid sequence. Secondary structure refers to the locally folded structure: alpha helix and beta sheets. Tertiary structures are three-dimensional structures formed due to interaction between side groups and quaternary structures are due to interaction between two or more polypeptide chains.
