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.
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
Sucrose (table sugar) contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose undergoing isomerization to an aldehyde, or fructose to alpha-hydroxy-ketone form. Sucrose is thus a non-reducing sugar which does not react with Benedict's reagent.
Therefore, fructose-1-phosphate accumulates with the corresponding reduction of intracellular Pi available for phosphorylation reactions in the cell. This is why fructose is contraindicated for total parenteral nutrition (TPN) solutions and is never given intravenously as a source of carbohydrate. It has been suggested that excessive dietary ...
Reality TV producer Mark Burnett ('The Apprentice," "The Voice," and "Survivor") was named the UK special envoy by President-elect Donald Trump.
"The mystery has finally been solved," Congo's health ministry says, after an unidentified disease outbreak started killing mainly women and children in a remote region.
Foods with >3 g of fructose per serving are termed a 'high fructose load' and possibly present a risk of inducing symptoms. However, the concept of a 'high fructose load' has not been evaluated in terms of its importance in the success of the diet. [17] Foods with high fructose-to-glucose ratio. Glucose enhances absorption of fructose, so ...
