Oxytocin

Oxytocin

$60.00

Oxytocin is a cyclic nonapeptide (nine amino acids) with the molecular formula C43H66N12O12S2 and a molecular weight of 1,007.19 g/mol. Its amino acid sequence — Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2 — forms a ring through a disulfide bond between the two cysteine residues at positions 1 and 6. First synthesized in 1953, it was the first peptide hormone ever produced in a laboratory. Oxytocin is classified as both a neuropeptide and a peptide hormone, naturally produced in the hypothalamus. It is supplied as a white to off-white lyophilized powder, highly soluble in water, and identified by CAS number 50-56-6. This product is strictly for research purposes only.

Overview

Oxytocin is a cyclic nonapeptide — a chain of nine amino acids arranged in a ring shape, held together by a disulfide bond between two cysteine residues. Its sequence is Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2, with a molecular weight of 1,007.19 g/mol and the formula C43H66N12O12S2. The ring structure formed by the disulfide bridge gives the molecule its characteristic stability.

Oxytocin was first isolated and synthesized in 1953, making it the first polypeptide hormone ever synthesized in a laboratory. The compound is naturally produced in the hypothalamus region of the brain and is classified as both a neuropeptide and a peptide hormone. In its research-grade form, oxytocin appears as a white to off-white lyophilized powder that is highly soluble in water.
