Oxidative stress is considered to be a major contributor to a wide range of diseases, such as cardiovascular disease, Alzheimer's disease, Parkinson's disease, rheumatoid arthritis, neurodegeneration in motor neuron diseases and the pathologies caused by diabetes. Oxidative damage in DNA may cause harmful mutations and cancer, while protein damage may result in protein degradation, enzyme inhibition and denaturation. Organisms have a complex system of antioxidant metabolites and enzymes to prevent oxidative damage to cellular components. Antioxidants are compounds that inhibit oxidation. Antioxidant vitamins can be found in certain foods such as fruits, vegetables, eggs, nuts and legumes. This book is compiled in such a manner, that it will provide in-depth knowledge about antioxidants. It includes some of the vital pieces of work being conducted across the world, on various topics related to this area of study. It is a vital tool for all researching or studying antioxidants as it gives incredible insights into emerging trends and concepts.
