Reagen Benedict

Benedict's reagent

Reagen Benedict adalah reagen kimia yang dinamakan sempena seorang ahli kimia Amerika, Stanley Rossiter Benedict. Reagen Benedict digunakan sebagai ujian untuk kehadiran gula merah. Ini termasuk semua monosakarida dan banyak disaccharides, termasuk laktosa dan maltosa. Lebih-lebih lagi, ujian Benedict akan mengesan kehadiran aldehid, dan alfa-hidroksi-keton, termasuk yang terjadi pada beberapa ketosis. Oleh itu, walaupun fruktosa ketose tidak mengurangkan gula, ia adalah alpha-hydroxy-ketone, dan memberikan ujian positif kerana ia ditukarkan kepada aldosa glukosa dan mannose oleh asas dalam reagen. Ujian positif dengan reagen Benedict ditunjukkan oleh perubahan warna dari biru jernih hingga mendakan bata-merah. Satu liter reagen Benedict boleh disediakan dari 100 g natrium karbonat anhydrous, 173 g sodium sitrat dan 17.3 g tembaga sulfat pentahydrate. Ia sering digunakan sebagai ganti penyelesaian Fehling. Reagen Benedict mengandungi ion tembaga biru yang dikurangkan kepada ion tembaga. Ini dicetuskan sebagai oksida tembaga merah yang tidak larut dalam air.

Benedict's reagent 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, 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. A positive test with Benedict's reagent is shown by a colour change from clear blue to a brick-red precipitate. One litre of Benedict's reagent can be prepared from 100 g of anhydrous sodium carbonate, 173 g of sodium citrate and 17.3 g of copper sulfate pentahydrate. It is often used in place of Fehling's solution. Benedict's reagent contains blue copper ions which are reduced to copper ions. These are precipitated as red copper oxide which is insoluble in water.
