it is a carbonyl in disguise), identification of reducing sugars becomes easier.Here is an example from Wikipedia, it is Maltose, the same as your third compound. Non-reducing sugars do not have an OH group attached to the anomeric carbon and therefore they cannot reduce other compounds. Most of non-reducing sugars are polysaccharides whereas others are disaccharides. Sucrose is a glucose carbon connected at the anomeric carbon to a fructose carbon. However, reducing sugars contain free anomeric carbon. You can read the details below.

A disaccharide can be a reducing sugar or a non-reducing sugar. A sugar without a hemiacetal is a non-reducing sugar. The specificity of enzymes allows one monosaccharide, glucose, to be the building block for both starch, which we think of as a major source of energy in our foods, and cellulose, which we regard as a structural material in trees and a major component of paper. Chemical interactions of food components emulsion, gelation, browning. One of the most prominent properties of non-reducing sugars is that they do not generate any compounds with an aldehyde group in a basic aqueous solution. Although caramelization can occur at milder temperatures, it is favored at temperatures higher than 120C. test for reducing sugars sciencing april 17th, 2019 - once added to the test solution reducing sugars reduce the blue copper sulphate from the benedict s solution to a red brown copper sulphide which is seen as the precipitate and is responsible for the color change non reducing sugars cannot do this this particular test only provides Number of Views: 3435. can anyone help me out?
