Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Stanley Rossiter Benedict (17 March 1884 – 21 December 1936) is an American chemist best known for discovering Benedict's reagent, a solution that detects certain sugars. Benedict was born in Cincinnati, and went to the University of Cincinnati. After a year, he went to Yale's Department of Physiological Chemistry for training in metabolism and physiology. Benedict's reagent (also called Benedict's solution or Benedict's test) is a chemical reagent named after an American chemist, Stanley Rossiter Benedict. Benedict's reagent is used as a test for the presence of reducing sugars. This includes all monosaccharides and many disaccharides, including lactose and maltose. Even more generally, Benedict's test will detect the presence of aldehydes (except aromatic ones), and alpha-hydroxy-ketones, including those that occur in certain ketoses. Thus, although the ketose fructose is not strictly a reducing sugar, it is an alpha-hydroxy-ketone, and gives a positive test because it is converted to the aldoses glucose and mannose by the base in the reagent.
