In organic chemistry, Keller's reagent is a mixture of anhydrous (glacial) acetic acid, concentrated sulfuric acid, and small amounts of ferric chloride, used to detect alkaloids. Keller's reagent can also be used to detect other kinds of alkaloids via reactions in which it produces products with a wide range of colors.
Reducing form of glucose (the aldehyde group is on the far right). A reducing sugar is any sugar that is capable of acting as a reducing agent. [1] In an alkaline solution, a reducing sugar forms some aldehyde or ketone, which allows it to act as a reducing agent, for example in Benedict's reagent.
The products of sucrose decomposition are glucose and fructose, both of which can be detected by Benedict's reagent as described above. Starches do not react or react very poorly with Benedict's reagent because of lesser number of reducing sugar components that occur at the ends of the carbohydrate chains.
Keller's reagent can refer to two different reagents: Keller's reagent (metallurgy) , used to etch aluminum alloys Keller's reagent (organic) , used to detect alkaloids
Added sweeteners have been blamed, at least in part, for our nation's obesity epidemic, with sugary beverages and virtually anything containing high-fructose corn syrup getting an The Link Between ...
Fructose is also 73% sweeter than sucrose at room temperature, allowing diabetics to use less of it per serving. Fructose consumed before a meal may reduce the glycemic response of the meal. [65] Fructose-sweetened food and beverage products cause less of a rise in blood glucose levels than do those manufactured with either sucrose or glucose. [12]
In metallurgy, Keller's reagent is a mixture of nitric acid, hydrochloric acid, and hydrofluoric acid, used to etch aluminum alloys to reveal their grain boundaries and orientations. [1] It is also sometimes called Dix–Keller reagent , after E. H. Dix, Jr., and Fred Keller of the Aluminum Corporation of America , who pioneered the use of this ...
