Generally, Benedict's test detects the presence of aldehyde groups, alpha-hydroxy-ketones, and hemiacetals, including those that occur in certain ketoses. In example, although the ketose fructose is not strictly a reducing sugar, it is an alpha-hydroxy-ketone which results to a positive test because the base component of Benedict converts it ...
Bifidobacterium in the human intestine have been found to contain type I chain lacto-N-biosidases capable of cleaving lacto-N-tetraose to lactose-N-biose and lactose. [ 11 ] Lacto- N -tetraose is a non-competitive food source for B. infantis with other enteric bacteria lacking the required proteins and incapable of degrading the sugar into ...
Reducing disaccharides like lactose and maltose have only one of their two anomeric carbons involved in the glycosidic bond, while the other is free and can convert to an open-chain form with an aldehyde group. The aldehyde functional group allows the sugar to act as a reducing agent, for example, in the Tollens' test or Benedict's test.
The digestive system is unable to process the lactose sugar, and the unprocessed sugars in the gut produce the symptoms of lactose intolerance. Lactose intolerance is not an allergy , because it is not an immune response, but rather a sensitivity to dairy caused by a deficiency of lactase enzyme.

Since its discovery in 1904 until the 1960s, the Wöhlk test has mainly been used to detect the reducing disaccharide lactose in urine in medical laboratories. Although there were already a number of wet-chemical detection methods to identify sugars, such as the Fehling or Benedict test , those analyses could only differentiate between reducing ...
