Lehninger, The New Edition Clear writing and illustrations…Clear explanations of difficult concepts…Clear communication of the ways that biochemistry is currently understood and practiced. For over 35 years, in edition after bestselling edition, Principles of Biochemistry has put those defining principles into practice, guiding students through a coherent introduction to the essentials of biochemistry without overwhelming them.

February 2013 Hardback 978-1-4641-0962-1
The new edition brings this remarkable text into a new era. Like its predecessors, Lehninger Principles of Biochemistry, Sixth Edition strikes a careful balance of current science and enduring concepts, incorporating many new research findings, but focusing on those that help illustrate important principles of biochemistry. With this edition, students will encounter new information emerging from high throughput DNA sequencing, x-ray crystallography, and the manipulation of genes and gene expression, and other techniques. In addition, students will see how contemporary biochemistry has shifted away from exploring metabolic pathways in isolation to focusing on interactions among pathways. They will also get an updated understanding of the relevance of biochemistry to the study of human disease (especially diabetes) as well as the important role of evolutionary theory in biochemical research. These extensive content changes, as well as new artwork, make this edition of Lehninger Principles of Biochemistry the most impressive yet.

Lehninger Teaching Hallmarks Students encountering biochemistry for the first time often have difficulty with two key aspects of the course: approaching quantitative problems and drawing on their previous studies of organic chemistry. Those same students must also learn a complex language, with conventions that are often unstated. As always, Principles of Biochemistry helps students cope with these challenges:
Focus on Chemical Logic n
Section 13.2, Chemical logic and common biochemical reactions, discusses the common biochemical reaction types that underlie all metabolic reactions, helping student to connect organic chemistry with biochemistry.
NEW chemical logic figures highlight the conservation of mechanism and illustrate patterns that make learning pathways easier. Chemical logic figures are provided for each of the central metabolic pathways: glycolysis (Fig 14-3), citric acid cycle (Fig. 16-7), and fatty acid oxidation ( Fig 17-9).
F I G U RE 1 6 - 7
S i x th E dition
Mechanism figures feature step-by-step descriptions to help students understand the reaction process. These figures use a consistent set of conventions introduced and explained in detail with the first enzyme mechanism encountered.
Problem-Solving Tools n In-text Worked Examples take students through some of the most difficult equations step by step. New worked examples appear in Chapters 1, 2, and 19. n More than 600 end-of-chapter problems (over 75 of them new) give students further opportunity to practice what they have learned. n Data Analysis Problems (one at the end of each chapter), contributed by Brian White of the University of Massachusetts–Boston, encourage students interpret data from the literature.
Key Conventions The text highlights clear statements of many assumptions and conventions that students are often expected to assimilate without being told (for example, peptide sequences are written from amino-to carboxyl-terminal end, left to right; nucleotide sequences are written from 5’ to 3’ end, left to right).
