Differentiate between the following :
Secondary and tertiary structure of protein

Explanation

To differentiate between the secondary and tertiary structures of proteins, we can follow these steps:

### Step 1: Definition of Secondary Structure
The secondary structure of a protein refers to the local folding of the polypeptide chain into specific shapes, primarily alpha helices and beta sheets. These structures are stabilized by hydrogen bonds between the backbone atoms in the polypeptide chain.

### Step 2: Definition of Tertiary Structure
The tertiary structure of a protein is the overall three-dimensional shape of a single polypeptide chain. It results from the interactions among various side chains (R groups) of the amino acids, including hydrogen bonds, ionic bonds (salt bridges), disulfide bonds, and hydrophobic interactions.
