The popular American Chemical Society Molecule of the Week now has its own mobile app.

WASHINGTON, April 15, 2010 — The American Chemical Society’s (ACS) Molecule of the Week (MOTW) is one of the most popular destinations on the ACS website, and it may be getting more popular. The reason: ACS has unveiled a MOTW mobile application for iTunes.

Current MOTW enthusiasts –– and everyone else interested in science –– can download the new app from

Each week, the MOTW presents a different molecule, with a description, image of the molecular structure, links to records from the Chemical Abstracts (CAS) RegistrySM,

and other information. From allicin (the molecule responsible for the odor of crushed garlic) and ascorbic acid (vitamin C) to xylitol (the sugar substitute) and zingerone (which gives ginger a hot taste), there are always fascinating molecules that relate chemistry to everyday life.

The new app automatically delivers these features (plus a game quiz) to the convenience of an iPhone, iPod Touch, and the just-released iPad. There are other cool features, too — such as a clue that appears with a shake of an iPhone or iPod — all designed to make the MOTW iPhone app not only informative but fun, too.
