Abstract
The paper relates that high levels of dichloroacetate, a drinking water disinfectant and by-product, depleted glutathione-s-transferase's activity in studied rats. The paper reveals that those with a hereditary deficiency in the gene or enzyme appeared to have an increased risk of developing chronic obstructive pulmonary disorder (COPD). The paper looks at a study that connected the glutathione gene to the development of childhood asthma. The paper discusses another study that illustrated the significance of the glutathione gene in delaying the onset of breast cancer.
From the Paper
"Dichloroacetate or DCA is a drinking water disinfectant and by-product commonly found in municipal water supplies (Saghir 2002). It is a metabolite of chlorinated industrial solvents and many pharmaceuticals. It is quickly and completely absorbed from the gastrointestinal tract and in extensively metabolized in both rodents and humans by major metabolites. Metabolism occurs primarily in the liver, mediated by Glutathione-s-Transferase GST [zeta] (GSTZ-1) (12). DCA inhibits Glutathione and prolonged exposure of rodents to DCA reduces metabolism and depletes immuno-reactive Glutathione protein levels from the liver."

Abstract
In this article, the writer examines the general structure of enzymes. The writer discusses how enzymes act to speed up chemical reactions. The writer details the six major groups of enzymes: oxidases, lysases, ligases, isomerases, transferases and hydrolases.
From the Paper
"Enzymes are special proteins which act to speed up chemical reactions because many chemical reactions required for cells to function normally would not take place at the temperature and pH found in the body. The protein part of the enzyme without any co-factors or prosthetic groups attached is known as the apo-enzyme. Not all enzymes have co-factors or prosthetic groups. Co-factors are small inorganic or organic molecules which are required for enzymatic activity of the apo-enzyme such as the copper loosely bound to lysine oxidase ... "
