E-Book Overview
Renowned for its student-friendly writing style and fresh perspective, John McMurry's ORGANIC CHEMISTRY WITH BIOLOGICAL APPLICATIONS offers full coverage of the foundations of organic chemistry--enhanced by biological examples throughout. Based on user feedback, McMurry continues to discuss the organic chemistry of biological pathways and now adds two dozen additional organic chemistry topics, as well as new problems, new illustrations, and new essays. Media integration with Organic OWL, a customizable online learning system and assessment tool, reduces faculty workload, facilitates instruction, and helps students master concepts through tutorials, simulations, and algorithmically generated homework questions.
