Chem. 205A (Fall 2006): The Chemistry of Biology Instructors: Joan S. Valentine and Jon M. Fukuto T, Th 2-4 3440 MSB Chemistry 205A is a graduate and advanced undergraduate course that focuses on the intimate chemical details of important biological processes. The course provides the basis for a fundamental chemical understanding of select biological processes. Specifically targeted are students interested in the chemistry-biology interface. Thus, chemistry majors seeking to develop a chemical understanding of biological processes or biology/biochemistry majors wishing to extend their chemical knowledge of these processes are encouraged to enroll. Below are several topics that are covered. 1. Amino acids: The functional group chemistry of amino acids is covered. The biological processes that rely on this chemistry are also discussed. 2. Nucleic acids: A brief overview of the chemistry of the components of RNA and DNA (phosphate, ribose and the bases) is given with an emphasis on DNA as a chemical target in disease states. 3. Lipids and fatty acids: The chemistry of lipid oxidation and its role in toxicity and cell signaling is covered. 4. Sugars and carbohydrates: The chemical properties of sugars are discussed along with the importance of this chemistry in cell signaling/recognition. 5. Cofactors and prosthetic groups: The chemistry of flavins, hemes, pterins, metals and other important species is discussed. The important catalytic and signaling functions associated with this chemistry are covered. 6. Small molecule chemistry/biology: Recent advances in small molecule signaling and toxicity are discussed. Of special interest are the small molecule diatomics NO, CO and O2 as well as H2S and CO2. 7. Redox chemistry in biology: The role of redox chemistry in biology is discussed. Specifically, the importance of thiols in redox biology is emphasized.
