This new book provides comprehensive coverage of the subjects of deuterium oxide and deuteration in biosciences, with an emphasis on the biochemical, biomedical, and pharmacological aspects. Deuterium oxide and deuteration effects also offer various implications for health-related issues, including diseases, vaccines and drugs. Organized in six sections, the chapter topics include the role of regular and heavy water in biosciences, and their implications to biomolecules, biochemical processes, health-related research, and pharmacology. Due to the broad scope, the book may be used as a supplemental text for upper-level undergraduate and graduate courses in the related fields of biochemistry, biology, biomedical sciences, biophysics, and pharmacology. Researchers and pharmaceutical industry professionals will also find the content useful in order to gain knowledge and better understand the implications of deuterium oxide and deuteration research.
