β-Endorphin, human is an endogenous opioid neuropeptide derived from the pro-opiomelanocortin (POMC) precursor, consisting of 31 amino acids. It acts as a high-affinity ligand for μ opioid receptors, mediating potent analgesia, mood regulation, and immune modulation in humans. This peptide plays a critical role in stress responses, reward pathways, and gastrointestinal motility. In pharmacological research, human β-Endorphin serves as a foundational tool to study opioid receptor activation mechanisms, structure-activity relationships, and the development of analgesic and anti-addiction therapies. Its natural origin and receptor specificity underscore its significance in understanding endogenous pain modulation, psychiatric disorders, and translational medicine.
