ANTIOXIDANT AND FREE RADICAL MINI-ESSAY Antioxidants are man-made or natural molecules or substances which helps in inhibiting or delaying some chemical reactions like oxidation which results in the formation of free radicals leading to chain reaction which consequently results into cell damage(Singleton et al 1999). Antioxidants prevent the free radical formation by inhibiting or means of folin-ciocalteu reagent." Methods in enzymology 299 (1999): 152-178. 2.Witting Lloyd A.

Materials/resources: • Chemistry lessons and web-based research • Relevant web sites, including: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3249911/ http://www.healthchecksystems.com/antioxid.htm • Periodic table Atoms, Molecules, Bonding and Beyond. 2014. EPIC (Educational Policy Improvement Education, used with permission). Apply Your Knowledge After researching reliable sources on the topic of antioxidants and free radicals, write a 1 -2 page paper (approximately 400 words) in which you 1) explain how the intake of antioxidants prevents formation of free radicals, 2) give a specific example of an illness that is cured by an antioxidant, and 3) explain how this reaction may be connected to bond breaking or formation. Support your position with evidence from your research. Be sure to include the oxidized chemical species and formation of new bonds in the example you select. Your paper should: • Provide a concluding statement or section that supports the information or explanation provided. • Discuss limitations of the supporting studies. • Use discipline-specific vocabulary. • Cite your sources correctly in the text of your paper and create a Works Cited page using MLA format with the web address of your sources following each citation.
