More than twenty synthesized S-containing amino acids and peptides with biological interests, have been measured by direct inlet system of the mass spectrometer. Most of these compounds have the large molecular ion abundances and give the reproducible fragmentations. The mass spectral-fragmentation mechanisms of systematically synthesized S-alkyl-l-cysteines, S-alkyl-l-cysteine sulphoxides, S-alky
已经通过质谱仪的直接入口系统测量了二十多种具有生物学意义的合成的含S氨基酸和肽。这些化合物大多数具有大的分子离子丰度,并产生可再现的碎片。系统合成的S-烷基-1-半胱氨酸,S-烷基-1-半胱氨酸亚砜,S-烷基-2-甲基-dl-半胱氨酸,缩水甘油基-S-烷基-dl-半胱氨酸和环状硫的质谱裂解机理提出了含氨基酸的氨基酸等。
