Peptide synthesis is the process of creating peptides, which are short chains of amino acids linked by peptide bonds. This process can occur naturally in living organisms or be performed artificially in laboratories. The artificial method often involves solid-phase synthesis, where amino acids are sequentially added to a growing chain attached to a solid support. In laboratory settings, peptide synthesis is crucial for research and pharmaceutical development. It allows scientists to produce specific peptides for studying biological functions or developing new drugs. Techniques like solid-phase peptide synthesis (SPPS) and liquid-phase synthesis are commonly used to achieve this.
