This text describes the roles of naturally occuring antioxidants in living cells. It focuses on stoichiometric antioxidants - small molecules that the cell can rapidly produce and transport into regions of oxidative stress. Naturally Occurring Antioxidants reflects the growing interest in these compounds among the scientific community. This book explores how quantitative measures can provide a more complete understanding of important substances and their reactions, allowing us to address some crucial environmental and health questions. Environmental chemists and toxicologists, general organic and inorganic chemists, life and environmental scientists, environmental and chemical engineers, nutritionists, and students of environmental chemistry will all find Naturally Occurring Antioxidants to contain thought-provoking topics for further study.
