Biomolecules
Natural Products
Organic chemistry had its genesis in the study of naturally occurring substances, and this remains a constant source of information and intellectual challenge. In this section some of the most interesting and important classes of natural products will be discussed.
At various points throughout this text, links to supplementary information or special topics will be located in shaded boxes of this kind.
Problems and Other Resources
The following problems focus on concepts and facts associated with the trearment of natural product chemistry in this text.
Many excellent web sites devoted to various aspects of biochemistry exist. Instructional tutorials combined with molecular model visualization have been created and implemented. Some of the sites have self testing quizzes. The following list is far from complete, but it contains links to pages which enhance and extend the treatment of topics provided in this text.
