"Much of organic chemistry is based on the ability of suitably structured chemicals to bind together through the formation of covalent bonds. Biochemistry is replete with exam ples of enzymatically catalyzed reactions in which normal body constituents can be linked through covalent bonds during the process of intermediary metabolism. The finding that xenobiotic chemicals that enter the body from the environme ..."

"Provides a complete understanding of how our bodies respond to toxicants, and the principles used to assess the health risks of specific exposure scenarios Toxicology and Risk Assessment: A Comprehensive Introduction, Second Edition reflects recent advances in science and technology, and provides the scientific background and methodological issues to enable the reader to understand the basic principles in toxicology and to evaluate the ..."
"This new book, written by two outstanding scientists in the field, describes the basic principles of toxic mechanisms and organ toxicity, providing detailed information on specific mechanisms or chemicals for exemplification. The goal is to provide sufficient information that the reader becomes familiar with the basic concepts in toxicology to enable him or her to understand the basic principles in toxicology and to evaluate the risks a ..."
"Genotoxic carcinogens can lead to DNA mutations with the potential to cause cancer. Typically, a series of mutation events are needed before malignancy occurs so a single, small exposure may not result in disease. Also, cells have an armoury of defence mechanisms which, to a degree, counter the effects of mutagens. Distinguishing the point at which exposure to a carcinogen increases mutation rates beyond the background level is challeng ..."

"Historically we have separated the disciplines of Chemistry and Biochemistry by recognizing that the distinguishing characteristic of Biochemistry is the catalysis of reactions by enzymes. Enzymes permit metabolic reactions which would otherwise require extremes of temperature, pressure or pH, often associated with Chemistry, to proceed under ambient conditions of the body. Under some conditions chemical reac ..."

"The most complete and up-to-date survey of this important superfamily of enzymes, including the first ever coverage of the forms involved in steroid hormone biosynthesis. The components of the enzyme system, the reaction mechanisms involved, and the evolution and nomenclature are analyzed, as is the hepatic microsomal enzyme in a large number of species, illustrating the very wide implications for life processes."
