Drug Development and Toxicology (High-performance liquid chromatography) - Essay Examplen from the twenty-four hours of the accident to the 5th day sampling, it can be seen that the presence of 4,5-dihydrodiol is evident in all old age in the range of 0.1 to 0.2 nmol/ml. the second metabolite 7,8-dihydrodiol has the most presence immediately after the accident but slowly diminish through the days. The metabolite 7,8-diol-9,10 epoxide on the other hand has the least presence on the samples. It is even unobserved during the first two days of the accident.Epoxide Hyrdolase contribute to the biodegradation of many organic compounds such(prenominal) as benzoapyrene.(Loo, et al. 2006). This enzyme has the ability to detoxify a wide range of organic potential genotoxic epoxides with diverse structures (ARand, et al. 2003). It can modulate the effects on the binding of benzoapyrene to the DNA structures (Carcinogenesis, 1983). It plays important roles in the metabolic activation of benzoa pyrene to carcinogens and mutagens (Thakker, et al. 1977).Metabolism of Benzo a) Pyrene leads to formation of various compounds such as benzoa pyrene 4,5-dihydrodiol, ortho quinone and benzoapyrene 7,8-dihydrodiol-9,10-epoxide (Wood, et al., 1976). The first crop is less or considered as non-mutagenic as compargond to the other product which are the epoxide diol metabolites. The role of epoxide hydrolase is important such that it makes the benzo a pyrene derivatives to result to the non-mutagenic products. With this, there is less threat to genic mutation and other health risks (Wood, 1981).Mr X is may have the possibility to develop cancer. There are three products for the metabolic pathway for benzoapyrene where the product 7,8-doil-9,10-epoxide provides the biggest threat to human health due to its carcinogenic and mutagenic effect (Ruan, 2006). However, with the sampling and retention times considered, there are more products for 4,5-dihydrodiol produced based on the UV absorb ance wavelength in detecting their presence.Benzo-pyrene are polycylic aromatic hydrocarbons with
