Now in its fifth edition Biochemistry and Molecular Biology features a new author team, who have retained the much-praised clarity of previous editions, while adding a more biomedical focus and incorporating a discussion of recent developments in research. A new chapter on the general principles of nutrition emphasises the key principles underlying complex metabolic pathways, enabling students to appreciate an integrated view of human metabolism and nutrition. Also new to the fifth edition, a chapter on the control of gene expression reflects our increasing understanding of the importance and power of gene regulation. With an integrated approach covering both biochemistry and molecular biology, complemented by frequent diagrams and clear explanations, and all presented in a broader cellular context, this text is the perfect introduction for any student new to the subject.
