what is a peptide bond?

A peptide bond is a chemical bond that joins two amino acids together to form a protein. It is formed when the carboxyl group (-COOH) of one amino acid reacts with the amino group (-NH₂) of another amino acid, releasing a molecule of water.

Formation of a Peptide Bond:

• Amino Acid 1 + Amino Acid 2 → Dipeptide + H₂O

Importance of Peptide Bonds:

1. Link amino acids to form proteins.

2. Help build enzymes, hormones, and body tissues.

3. Are essential for growth, repair, and various biological functions.

In simple terms: A peptide bond acts like a link or bridge between amino acids, allowing them to join together and form proteins.
