CHEM 2380.001 October 2007 Lycopene is a terpene and is a member of the carotenoid family (eight isoprenoid untis where the arrangement is reversed at the center of the molecule (dcg-carot.unibe.ch/nomen.htm))—it is a natural fat- soluble pigment found in plants and microorganisms, where it protects against the toxic effects of oxygen and light. The average human daily intake of lycopene is 25 mg (50% from processed tomato products). Only plants and microorganisms can synthesize lycopene. (pdrhealth.com). Lycopene is an isomer of β-Carotene. Lycopene found in human plasma is usually a 50/50 mix of cis and trans isomers. Lycopene has the highest antioxidanat activity of all the carotenoids; it can trap peroxy radicals, inhibit the oxidation of DNA, inhipit lipid peroxidation, and in some studies, inhibit the oxidation of LDLs. Until recently it was believed that lycopene and other beta carotenes reduced the risk of certain types of cancer, especially prostate cancer,

Unformatted text preview: however, a recent study carried out by the National Cancer Institute and Fred Hutchinson Cancer Research Center shows that high consumption of lycopene may actually incrase the risk of aggressive prostate cancer (ScienceDaily). Its red color is due mainly to its conjugated bonds. References: American Associatoin for Cancer Research. “No Magic Tomato?
