Oxytocin is a cyclic nonapeptide (C43H66N12O12S2) that functions as both a hormone and a neurotransmitter. Primarily synthesized in the paraventricular and supraoptic nuclei of the hypothalamus and released via the posterior pituitary gland, it is a key modulator of smooth muscle contraction and social cognition. Research applications include investigations into G-protein-coupled receptor (GPCR) signaling, phospholipase C (PLC) pathways, and myometrial cell activation.
