Antioxidants are molecules that act against the process of oxidation. The large, complex antioxidant molecules can bond with the unpaired electrons of free radicals, effectively neutralizing the oxidation process. They act by inhibiting reactions caused by the oxidation process. They neutralize ROS by donating one of their own electrons. They are stable and help to prevent further cell damage. High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
