Chemistry at Kimball's Biology : Includes acids and bases, bond energy, elements and atoms, hydrogen bonds, mixtures and compounds, parts per million (PPM), etc., prions, and more.
Atoms and Molecules : Two pages that explain the basics of chemistry necessary to under-standing of biological concepts and evolutionary theory. This is a primer, not an intensive course.
Kimball's Biochemistry : Thorough coverage of the basics of biochemistry including many topics such as ATP, Bioluminescence, Cellular respiration, Enzymes, Metabolism, Photosynthesis, The Urea cycle and more.
Biochemistry in 3D :
Interactive tutorials using 3D structures to teach concepts in Biochemistry. It is designed to accompany Lehninger Principles of Biochemistry 3rd edition.
The Molecular Universe : This is a web book, some segments of which such as The Molecules of Life, will be of interest to students.
Chromatin Structure & Function : We often picture DNA as free-floating strands, but in the nucleus it's actually tightly wound around proteins called histones. A flurry of research is probing how chemical messengers coax this balled-up stuff, called chromatin, to unravel and send signals for making proteins.
BioChem Workbench : A revolutionary tool for biologists. Search many popular protein and nucleic acid sequence databases and access a wide variety of analysis and modeling tools, all within a point and click interface that eliminates file compatibility problems.
Whether it's the perfume of lilac blossoms or the stench of old gym socks, a smell is a matter of chemistry. Odor molecules wafting through the air dock with olfactory receptors in your nose, triggering nerve impulses that the brain perceives as a smell.
