Introduction

Ketones are formed through the metabolic process of ketogenesis in the liver, which happens when the body's glucose is low, and it turns to fat for energy. ketone /'ki?to?n/ is an organic compound with the structure R-C(=O)-R', where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group -C(=O)- (a carbon-oxygen double bond C=O). The simplest ketone is acetone (where R and R' are methyl), with the formula (CH3)2CO. Many ketones are of great importance in biology and industry.
