Eicosanoids are a diverse group of biologically active molecules derived from polyunsaturated fatty acid precursors. This volume draws together for the first time a series of overviews on the biosynthesis and functional significance of these and related compounds in a wide range of animals, plants, and micro-organisms. All chapters are written by recognized experts in their fields, and many make use of significant amounts of unpublished materials. This volume is aimed at advanced undergraduates and at researchers interested in lipid biochemistry and general plant and animal biology.Originally published in 1999.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
