Chemical Synthesis of Hormones,Pheromones and Other Bioregulators
Postgraduate Chemistry Series
The Postgraduate Chemistry Series of advanced textbooks is designed to provide a broad understandingof selected growth areas of chemistry at postgraduate student and research level. Volumes concentrateon material in advance of a normal undergraduate text, although the relevant background to a subjectis included. Key discoveries and trends in current research are highlighted, and volumes are extensivelyreferenced and cross-referenced. Detailed and effective indexes are an important feature of the series. Insome universities, the series will also serve as a valuable reference for final year honours students.
