This beautifully and consistently illustrated text gives students in an introductory course the most current presentation of biochemistry available. Written by a chemist and a biologist, the book presents biochemistry from balanced perspectives. Features: * Reorganisation of chapters resulting in a single text with some chapters eliminated, several shortened, and some combined. * New "Critical Developments in Biochemistry," "Human Biochemistry" and "A Deeper Look" boxes include; A Fad Diet-Low Carbohydrates, High Protein, High Fat, Fool's Gold and the Reductive Citric Acid Cycle-The First Metabolic Pathway?, Melittin-How to Sting Like a Bee, Telomeres- A timely End to Chromosomes, and Knockout Mice: A Method to Investigate the Essentiality of the Gene. * Much of the artwork is new or modified. Icons used in the previous edition for small molecules have been eliminated for a better over-all design. * Membrane Transport, formerly a chapter in the supplement, is now a chapter (10) in the text, making for a more logical link with the previous chapter (9) on membranes. * Introductory chapter on nucleic acids and recombinant DNA are now grouped together as Chapters 11-13 for a more cohesive presentation. * A new chapter (17) discusses proteins that turn chemical energy into the mechanics of movement. * 4-color molecular graphics developed specifically for the book give three dimension to many complex biomolecules. Colour-coding of the molecules makes them easy to identify.
