催产素是一种由9个氨基酸残基组成的多肽类激素,分子内形成1对二硫键,适用于产妇子宫收缩,产后止血。催产素原来的生产工艺是从猪脑垂体后叶中提取。1953年,美国化学家维格奥纳德(Vincent du Vigneand)等人合成了第一个天然多肽激素——含有二硫键的催产素,找到了将二硫键引入多肽分子的一条途径,并因此获得了1955年的诺贝尔化学奖。1958年7月,当人工合成结晶牛 Oxytocin is a polypeptide hormone consisting of 9 amino acid residues, forming a pair of disulfide bonds within the molecule, suitable for maternal uterine contractions, postpartum hemostasis. The original production process of oxytocin is extracted from the posterior lobe of porcine pituitary gland. In 1953, the American chemist Vincent du Vigneand et al. Synthesized the first natural polypeptide hormone, disulfide-containing oxytocin, and found a way to introduce disulfide bonds into polypeptide molecules. So won the 1955 Nobel Prize in Chemistry. July 1958, when artificial synthesis of crystalline cow
