Describe what do you understand by the primary and secondary structures of proteins.

Explanation

### Step-by-Step Solution

**Step 1: Understanding Primary Structure of Proteins**
- The primary structure of a protein refers to the specific sequence of amino acids that are linked together to form a polypeptide chain. Each protein has a unique sequence that determines its function and properties.
- Amino acids are connected by peptide bonds, which form during a dehydration synthesis reaction where the carboxyl group of one amino acid reacts with the amino group of another, releasing a water molecule.

**Step 2: Importance of Primary Structure**
- The primary structure is crucial because it dictates how the protein will fold and function. Any change in the sequence of amino acids can lead to a different protein or a malfunctioning protein, which can have significant biological consequences.
