Overview

This volume is part of a series, inaugurated in 1938, now referred to simply as ""Zechmeister"" after its founder, L. Zechmeister. It contains contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a reconized authority in his field, and provides a comprehensive and up-to-date review of the topic in question. This title looks at the chemistry of organic natural products. It is addressed to biologists, technologists and chemists alike. The series can be used by the expert as a source of information and literature citations, and by the non-expert as a means of orientation in a rapidly developing discipline.
