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.

1. Cracker Barrel. Cracker Barrels are open regular hours on Thanksgiving. You can eat a turkey dinner in the restaurant, or order a Thanksgiving family-size meal to go if you don’t feel like ...
Since both glucose and lactose molecules have an aldehyde group in the open-chain form, the result was positive in both cases. Only the Woehlk test allowed a safe differentiation between glucose and lactose. [4] Thus, a relatively harmless milk congestion could be differentiated from a dangerous gestational diabetes. With lactose, the tested ...
