Fundamentals of Biochemistry

Voet, Voet and Pratt's Fundamentals of Biochemistry, 5th Edition addresses the enormous advances in biochemistry, particularly in the areas of structural biology and Bioinformatics, by providing a solid biochemical foundation that is rooted in chemistry to prepare students for the scientific challenges of the future.  While continuing in its tradition of presenting complete and balanced coverage that is clearly written and relevant to human health and disease, Fundamentals of Biochemistry, 5e includes new pedagogy and enhanced visuals that provide a pathway for student learning.

Donald Voet received a Ph.D. in chemistry from Harvard University and did postdoctoral research in the Biology Department at MIT. Don took up a faculty position in the department of chemistry at the University of Pennsylvania, upon completing his postdoctoral work. He has been a visiting scholar at Oxford University, the University of California San Diego, and the Weismann Institute of Science in Israel.

Judith Voet received her Ph.D. from Brandeis University and did postdoctoral research at the University of Pennsylvania, Haverford College and the Fox Chase Cancer Center. She taught at the University of Delaware before moving to Swarthmore College. Together with Don Voet, she is Co-Editor-in-Chief of the journal Biochemistry and Molecular Biology Education.
