Chapter 24: The Chemistry of Life

Molecular Structures of the Molecules of Life
Visit this site to view three-dimensional molecular structures of the molecules of life. Click on the icon “Molecules of Life” to open a menu where additional molecules can be selected.

The Chemistry of Forgetting
Chemical changes occur in the brain, which enable us to remember events for long periods of time. Scientists have discovered the chemical reactions that make this possible. Click on the link about how memory can fail to hear a description of this process.

Nomenclature Carbohydrates
In order for scientists to effectively communicate with one another, rules for naming carbohydrates had to be established. This Web site contains the rules for naming carbohydrates. Click on the link for “Historical development of carbohydrate nomenclature” to read about the background for naming carbohydrates. Click on some of the other links to familiarize yourself with the process.

DNA and Molecular Genetics
Visit this site to learn more about DNA. This site includes diagrams, photos, interesting information about DNA and replication, as well as, additional links to find more information. Scroll down on this Web page to see the x-ray diffraction photograph of the DNA double helix. Then scroll down to the link that leads you through an animated replication of DNA.

Peering at a Machine that Pries Apart DNA
Visit this site to learn about the enzyme that separates DNA before replication. Scroll down to the drawing of the DNA strands and read the caption for a brief explanation of this process.

Chem Connection Modules
Visit this site to view animations on various chemistry topics and find out how the material presented relates to real world situations.
