Human Endogenous Metabolite

In Vitro Trichloroacetic acid (TCA) is a common drinking water disinfection byproduct that produces a spectrum of liver effects, including hepatomegaly and liver tumors, in mice. It is also an oxidative metabolite of trichloroethylene (TCE), a solvent used in degreasing with widespread environmental exposure, which also produces hepatomegaly and liver tumors in mice[3].
