Announcement \Chapter 8 Enzymes: Basic Concepts and Kinetics\ in Lubert Stryer's \Biochemistry\ (Fourth Edition) will be used as my major lecture material, which is available for you to Xerox from your TAs. Chapter 8 in Lehninger's“ Principles of Biochemistry can be used as a reference

Much of the catalytic power of enzymes comes from their bringing sub- strates together in favorable orientations in enzyme-substrate (ES)com- plexes. The substrates are bound to a specific region of the enzyme called the active site. Most enzymes are highly selective in their binding

Lipids are a class of nonpolar molecules that include the fats, cholesterol, fatty acids, lipid-soluble vitamins, waxes, soaps, glycerophospholipids, sphingolipids, and others. Lipids are found in the membranes of cells, the endoplasmic reticulum and in specialized fat storage cells called adipocytes. Example of lipids
