Ecdysone, known as the molting hormone of arthropods, was only isolated in 1954, and identified as a steroid in 1963. Here some 77 specialists provide an up-to-date summary of our knowledge of ecdysone. The chapters cover different fields of research including chemistry, analytics, biochemistry, molecular biology, genetics, and endocrinology, as well as biology. The book is an up-to-date reference on structures and a thorough review of the literature. Annotation copyright Book News, Inc. Portland, Or.
