Abstract :
Thiols play a fundamental role in cell biology, biochemistry and pharmacology. Altered thiol levels in body fluids are linked to specific pathological conditions. Glutathione is the most abundant intracellular low-molecular-mass thiol, playing an essential role in protecting cells from toxic species; other relevant thiol-containing compounds are homocysteine (Hcy), cysteine (Cys), cysteinylglycine (CysGly). Plasma aminothiols can be bound to proteins but they also occur free in the disulfide (symmetrical and mixed) and in the reduced forms. The simultaneous determination of these aminothiols, their precursor and metabolites is a useful tool in studying oxidative stress, metabolic and redox regulation. Many capillary electrophoresis methods have been proposed for this purpose, the aim of the present review is to support researchers in the choice of suitable methods for the determination of thiols in body fluids evaluating the different approaches and technologies proposed from the literature.
