Excerpt: Oxytocin ( ) is a mammalian hormone that acts primarily as a neuromodulator in the brain. Oxytocin has the distinction of being the very first polypeptide hormone to be sequenced and synthesized biochemically, by Vincent du Vigneaud et al. in 1953. Oxytocin is best known for its roles in female reproduction. It is released in large amounts 1) after distension of the cervix and uterus during labor, and 2) after stimulation of the nipples, facilitating birth and breastfeeding. Recent studies have begun to investigate oxytocin's role in various behaviors, including orgasm, social recognition, pair bonding, anxiety, and maternal behaviors. For this reason, it is sometimes referred to as the "love hormone." The word oxytocin is a corruption of the Greek, kytokin, "quick labor." Oxytocin is a peptide of nine amino acids (a nonapeptide). Its systematic name is cysteine-tyrosine-isoleucine-glutamine-asparagine-cysteine-proline-leucine-glycine-amine (cys - tyr - ile - gln - asn - cys - pro - leu - gly - NH2, or (CYIQNCPLG-NH2). The cysteine residues form a disulfide bond. Oxytocin has a molec...
