A peptide is a short chain of amino acids linked together by peptide bonds, forming the building blocks of proteins. Amino acids are organic compounds that contain an amine group (NH2) and a carboxyl group (COOH), along with a unique side chain (R group). Peptides typically consist of a few to several amino acids, while proteins are made up of long chains of amino acids. The specific sequence of amino acids in a peptide determines its unique properties and functions.
Peptides serve a wide range of essential roles in living organisms. They can act as signaling molecules, transmitting messages between cells and tissues. For example, hormones like insulin and growth hormone are peptides that regulate various physiological processes. Additionally, peptides can be components of enzymes, antibodies, and structural proteins, contributing to processes such as digestion, immune response, and cell structure. Due to their diverse functions and importance in biological systems, peptides have garnered significant attention in fields like medicine, biotechnology, and pharmaceutical research for their potential therapeutic applications and contributions to our understanding of biology.
