Understanding Polypeptide Bonds: The Building Blocks of Proteins
A polypeptide bond, or peptide bond, is a critical chemical linkage in biochemistry connecting amino acids to form polypeptides and proteins. This covalent bond arises when the carboxyl group of one amino acid reacts with the amino group of another, releasing water. It forms the backbone of protein structures, linking amino acids in a sequence determined by genetic information. This sequence defines the protein’s structure and function, ensuring resilience crucial for roles like catalysis, structure, and communication in organisms.
