Large quantities of HGA are excreted daily in the urine, where it oxidizes to benzoquinones, which in turn form the melaninlike polymers that cause the discoloration of urine.
Additionally, in vitro spontaneous reaction of benzoquinones [30, 31] and 15-deoxy-[[DELTA].sup.12,14]- prostaglandin J2 [32, 33] with GSH has been documented, and recently, the involvement of nonenzymatic GSH conjugation in conversion of microcystins (toxins produced by cyanobacteria) was reported [34].

These compounds belong to numerous chemical groups including trike-tones, terpenes, benzoquinones, coumarins, flavonoids, terpenoids, strigolactones, phenolic acids, tannins lignin, fatty acids and non-protein amino acids (Soltys et al., 2013).
One potential pathway to achieve a complex I-independent form of mitochondrial respiration was recently described by us and others and involves the use of short-chain benzoquinones. We observed that some of those compounds are able to partially restore mitochondrial electron flow under conditions of a dysfunctional complex I [45,46]; an observation that was later independently confirmed [47].
