摘要
谷胱甘肽是人体内重要低肽,具有许多生物功能。正常状态下,体内主要以还原型(GSH,-O_2CCH(NH_3^(+))CH_2CH_2C∶ONHCH(CH_2SH)C∶ONHCH_2CO_2H)存在,氧化型(GSSG、(-O_2CCH(NH_3^(+))CH_2CH_2C∶ONHCH(CH_2S-)C∶ONHCH_2CO_2H)_2)只占还原型浓度的～1%,并由谷胱甘肽氧化还原酶维持二者的平衡。近年来发现。
The preparation and XPS characters of rare earth chloride complexes with oxidized glutathione(GSSG) have been studied.The results indicate that all the oxygen atoms in GSSG are coordinated and the conformation change of the ligand is very little in the complexes. The BE peaks of 3d_(5/2) and 3d_(3/2) of lanthanide ions in the complexes show the satellite peaks.The mechanism,intensity and shift of the satellite peaks are discussed.
