Peptide chain, also known as a polypeptide chain, is a sequence of amino acids linked together by peptide bonds. It is a fundamental component of proteins, which are essential for the structure, function, and regulation of the body's tissues and organs. The primary structure of a protein is determined by the sequence of amino acids in its peptide chain. This sequence is encoded by genes and is crucial for the protein's biological activity. Peptide chains can vary in length, ranging from a few amino acids to thousands, and can fold into complex three-dimensional structures. The folding process is influenced by the sequence of amino acids and is essential for the protein's function. Peptide chains can also be modified post-translationally, adding further complexity to their structure and function. In summary, peptide chains are vital for the functioning of living organisms, playing a crucial role in various biological processes.
