About Peptides – The Definition of Peptides
Peptides are short chains of amino acids connected by peptide bonds. Amino acids serve as the fundamental building blocks of proteins, and peptides represent smaller, well-defined sequences typically consisting of 2 to 50 amino acids. Due to their precise structure and predictable biochemical properties, peptides are widely utilized in laboratory environments as analytical and research tools.
Peptides occur naturally in biological systems and are involved in a wide range of molecular and cellular processes, including receptor interactions, signal transduction, enzyme activity, and protein-to-protein communication. Their defined composition makes them particularly valuable for controlled scientific investigation.
