👉 In the context of biochemistry, a polypeptide is a long, highly branched protein molecule that consists of multiple amino acids linked together through a specific arrangement of hydrogen bonds. These chains are often used in biological processes to carry out functions such as catalysis and signal transduction. Polypeptides can be distinguished from other types of proteins by their length, which typically ranges from hundreds of amino acids to thousands or even millions of amino acids. They have the ability to form large peptide chains that
