Glutathione is the most abundant intracellular thiol (i.e., a compound containing a sulfhydryl [SH] group) and low molecular weight tripeptide found in living cells.* The antioxidant functions of Glutathione Reduced include recycling vitamins E and C and serving as an antioxidant in all types of tissues.*
The technique can reveal the presence of disordered regions and the flexibility of multidomain proteins by observing characteristics, such as large R g , expanded distance distribution functions (p(r)), and, for highly disordered proteins, the lack of a characteristic bell-shaped peak in Kratky plot ( Among the first SAXS-based studies of disordered proteins was structural characterization of the acid-denatured form of apo-cytochrome c , which was shown to behave as a random coil, being characterized by high R g (evaluated by SAXS) and Stokes radius R s values (determined by dynamic light scattering), the R g /R s ratio of 1.55 typical for a random-coil polymer, and the lack of the peak in the Kratky plot (Damaschun et al., 1991a)
