Abstract
The positive- and negative-ion mass spectra of [methionine]enkephalin and [leucine]enkephalin have been obtained by using a fast-atom-bombardment source described previously by Barber, Bordoli, Sedgwick & Tyler [(1981) J. Chem. Soc. Chem. Commun., in the press]. This technique has allowed the spectra to be obtained without conversion of the enkephalins into volatile derivatives. The fast-atom-bombardment spectra show good pseudo-molecular-ion sensitivity and fragmentation that can be interpreted on the basis of the known molecular structure.
摘要
使用先前由巴伯、博尔多利、塞奇威克和泰勒描述的快原子轰击源，已获得了[蛋氨酸]脑啡肽和[亮氨酸]脑啡肽的正离子和负离子质谱。[(1981年)《化学学会杂志：化学通讯》，即将发表]。该技术使得无需将脑啡肽转化为挥发性衍生物就能获得质谱。快原子轰击质谱显示出良好的准分子离子灵敏度和碎片，这些可以根据已知的分子结构进行解释。
