Biosynthesis of Sterol in Insects

Insects cannot synthesize sterols de novo, so they typically require a dietary source. Cholesterol is the dominant sterol in most insects, but because plants contain only small amounts of cholesterol, plant-feeding insects generate most of their cholesterol by metabolizing plant sterols. This book looks into the sterol metabolic pathway that occur in insects, side chain dealkylation studies and the different sterol utilization in hymenoptera, Hemiptera, and Diptera. A detail study is being looked into basically on Ecdysteroid Biosynthesis in Drosophila. We further looked into the different types of oxidation process.
