Common Name | Oxytocin 1-8 |
---|
Description | Oxytocin 1-8 is the fraction of Oxytocin which contains only Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu amino acid peptide. Oxytocin (sold as Pitocin, Syntocinon) is a mammalian hormone that acts primarily as a neurotransmitter in the brain. Also known as alpha-hypophamine (α-hypophamine), 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: 1) it is released in large amounts after distension of the cervix and vagina during labor, and 2) after stimulation of the nipples, facilitating birth and breastfeeding, respectively. Recent studies have begun to investigate oxytocin's role in various behaviors, including orgasm, social recognition, pair bonding, anxiety, trust, love, and maternal behaviors. |
