Typically defined as containing between 2 and 50 amino acids, they occupy a unique position in biochemistry: larger and more structurally complex than individual amino acids, yet smaller and more targeted in their action than full proteins.The Role of Peptides in BiologyPeptides are found throughout the human body and play a critical role in virtually every biological system. They act as signalling molecules, hormones, neurotransmitters, and enzyme regulators — orchestrating...
