Answer (1 of 2): reference: Reducing sugar - Wikipedia Sugars can be classified as "reducing" or "non-reducing" on the basis of the presence of FREE aldehyde (R-CH=O) or ketone (R2C=O) groups in its chemical structure. The presence of reducing sugars is determined chemically by test methods such as dinitrosallicillic (quantitative) and qualitative methods using Benedicts reagent, Fehlings solution and Tollens reagent. A non-reducing sugar is a sugar or carbohydrate molecule that doesn't have a free aldehyde or ketone group and thus cannot act as a reducing agent. Reducing sugars lowers the risk of developing obesity and diabetes. It is important to note that the reducing sugars can be identified by different tests like benedicts test and fehling solution test. The cyclic form of glucose is formed when the hydroxyl group on carbon 5 binds to the aldehyde group on carbon 1. In the highest quartile of mono+disaccharide intake (> 142 g) weight loss was 29.9 kg compared to 25.1 kg in lowest quartile (> 72 g).
