Featured Molecules November 2003

""
The WebWare molecules of the month are amylose and polystyrene, which are examined in JCE Classroom Activity #57: "Pondering Packing Peanuts Polymers". In the activity, students investigate polymers and their chemical composition. The structures below show several repeating units of the two polymers. The helical, 50-unit amylose shows the structure that complexes with iodine to produce the blue charge-transfer complex in the starch—iodine test.

Viewing Requirements

In addition to the static image, two fully manipulable versions (Jmol, MDLChime) of these molecules appear below. (The Jmol versions may take a few extra seconds to load, based on the speed of your Internet connection.)
