In solution, exposed to air and light, the reduced form gives up electrons and converts to GSSG, which is why an aqueous glutathione preparation begins losing its stated active from the moment it is mixed

It is synthesised using solid-phase peptide synthesis (SPPS) and purified through high-performance liquid chromatography (HPLC)
