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 ...
Two men in Tokyo, Japan died after choking on mochi around New Years, and now officials are warning others to take care when eating the treat.
In a hydrogen breath test, the most accurate lactose intolerance test, after an overnight fast, 25 grams of lactose (in a solution with water) are swallowed. If the lactose cannot be digested, enteric bacteria metabolize it and produce hydrogen, which, along with methane, if produced, can be detected on the patient's breath by a clinical gas ...
My heart! At the end when they were sleeping with her, I totally melted! This brought back so many memories for me of bringing home our babies and our Westies meeting them for the first time.
4. French Toast. Slightly stale bread is perfect for French toast. It soaks up the eggy custard without falling apart or turning to mush. Whisk together eggs, milk, a splash of vanilla, and a ...
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.
