Uniting the basic elements of analytical chemistry and organic chemistry with the biological processes that aid the survival of living organisms, this second edition of Chemical Defense in Nature explains how and why terrestrial animals and plants use toxic organic molecules. as a means of development, as well as of successful reproduction in the natural world, full of struggles and dangers. The new text also contains general information on the analysis techniques of these molecules and on some basic elements of organic synthesis, with which they can be prepared in the chemical laboratory. In this book, the biological processes, which aid the survival of the species of the two most important kingdoms, are analyzed from the chemical point of view.
