Chemistry surrounds us and is central to our understanding of everyday life. The chemicals and molecules that are highlighted on this page demonstrate the importance of chemistry in familiar and seemingly ordinary things and events. A new molecule will be added weekly, so keep checking back for interesting ways in which chemistry shapes our lives and our world. Special thanks to the American Chemical Society for their inspiring ACS “Molecule of the Week” feature. If you have any questions or comments, please feel free to contact Dr. David Hilmey.
