Featured Molecules: Quartz and Cholesterol

Randall J. Wildman University of Wisconsin–Madison Madison, WI 53715

June Featured Molecules The WebWare molecules of the month for June are from two articles in this issue. The article, “Cement: Its Chemistry and Properties”, found on p 623 and featured on the cover, dicusses the constituents of cement. Silica is one of the main components of cement, and the most common form of pure silica (SO2) is α-quartz. In “Bromination and Debromination of Cholesterol: An Inquiry-Based Lab Involving Structure Elucidation, Reaction Mechanism, and 1H NMR” (p 670), Grant and Latimer describe an experiment suitable for upper-level organic chemistry students. Fully manipulable (Chime) versions of these and other molecules are available at the Only@JCE Online Web site: http:// jchemed.chem.wisc.edu/JCEWWW/Features/WebWare/ MonthlyMolecules/2003/Jun/.
