Molecule of the Week


January 7, 2008

Tyrosol, or 4-(2-hydroxyethyl)phenol, is an antioxidant found in olive oil and other foods. It inhibits the effects of compounds such as oxidized LDL cholesterol. Furthermore, researchers have found that in some microbes, tyrosol acts as a quorum-sensing molecule. A quorum-sensing molecule coordinates activity among groups of many single-celled organisms, such as those that cause yeast infections.
