Chemotaxonomy applies systematic data on the molecular architecture of components of the bacterial cell to the solution of taxonomic problems. This has been a powerful tool since the 1950s, and a number of chemotaxonomic markers have been identified, ranging from molecules unique to the Prokaryotae or specific groups of bacteria to mechanisms or products of metabolism that characterize genera or species. The availability, and relative simplicity of techniques for amino acid analysis, for sequential analysis of polymers, for gas and thin-layer chromatography, for fermentation products and lipids, and so on, have made the systematic studies possible. These have led to a more effective definition of taxonomic groups based on biochemical assessment of cell wall composition, lipid composition of membranes, the types of isoprenoid quinones, the amino acid sequences of select proteins, and the characterization of proteins, such as the cytochromes and many other macromolecules.

Sickle Cell Anemia: A patient and his wife come in to see you with a concern. The patient has a history of sickle cell disease in his family, but neither of his parents have exhibited any symptoms. The wife is an immigrant from rural tropical Africa and has no idea if her family has any history of sickle cell disease. However the area she is from has a high incidence of sickle cell anemia in the population. The couple has 2 children, ages 4, 8 and would like to have another. Their kids don’t know about the history of the disease. The couple has come to you for advice on whether or not to have another child, and what to tell their children about the family medical history. [One 50 min class period for introduction, 50 min gel electrophoresis, and partial class period follow-up and final analysis]
