A new edition of the popular introductory textbook for biochemistry and molecular biology. * Contains substantial new material * Contains even more of the clear colour diagrams Completely up to date. Elimination of inessential material has permitted full coverage of the areas of most current interest as well as coverage of essential basic material. Areas of molecular biology such as cell signalling, cancer molecular biology, protein targeting, proteasomes, immune system, eukaryotic gene control are covered fully, but still in a clear student friendly style. This makes the book suitable for the most modern type of courses. WHAT'S NEW New or completely re-written chapters - 2. Enzymes 3. The structure of proteins 4. The cell membrane - a structure depending only on weak forces 13. Strategies for metabolic control and their applications to carbohydrate and fat metabolism 17. Cellular disposal of unwanted molecules 23. Eukaryotic gene transcription and control 24. Protein synthesis, intracellular transport and degradation 25. How are newly synthesised proteins delivered to their correct destinations? - Protein targeting 26. Cell signalling 27. The immune system 30. Molecular biology of cancer 33. The cytoskeleton, molecular motors and intracellular transport There are also several major insertions of new material, and minor editing to the rest of the book.
