Sorbitol (/ ˈ s ɔː (r) b ɪ t ɒ l /), less commonly known as glucitol (/ ˈ ɡ l uː s ɪ t ɒ l /), is a sugar alcohol with a sweet taste which the human body metabolizes slowly. It can be obtained by reduction of glucose, which changes the converted aldehyde group (−CHO) to a primary alcohol group (−CH 2 OH).
It is miscible in water, alcohol, ether, acetone, and ethylene glycol. [3] DEG is a widely used solvent. [4] It can be a normal ingredient in various consumer products, and it can be a contaminant. DEG has also been misused to sweeten wine and beer, and to viscosify oral and topical pharmaceutical products.
A reducing sugar is one that reduces another compound and is itself oxidized; that is, the carbonyl carbon of the sugar is oxidized to a carboxyl group. [2] A sugar is classified as a reducing sugar only if it has an open-chain form with an aldehyde group or a free hemiacetal group. [3]
In wine tasting, humans are least sensitive to the taste of sweetness (in contrast to sensitivity to bitterness or sourness) with the majority of the population being able to detect sugar or "sweetness" in wines between 1% and 2.5% residual sugar. Additionally, other components of wine such as acidity and tannins can mask the perception of ...
A wine fermented in oak barrels as opposed to stainless steel or concrete. Traditional with white Burgundies, some Chardonnays and some Champagne. Barrique French term for a 225 liter cask that is traditionally used in Bordeaux and now adopted worldwide Baumé French measurement of the sugar concentration in the juice or wine. Beeswing
Wine is a complex mixture of chemical compounds in a hydro-alcoholic solution with a pH around 4. The chemistry of wine and its resultant quality depend on achieving a balance between three aspects of the berries used to make the wine: their sugar content, acidity and the presence of secondary compounds.
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.
In enzymology, aldose reductase (or aldehyde reductase) (EC 1.1.1.21) is an enzyme in humans encoded by the gene AKR1B1.It is an cytosolic NADPH-dependent oxidoreductase that catalyzes the reduction of a variety of aldehydes and carbonyls, including monosaccharides, and primarily known for catalyzing the reduction of glucose to sorbitol, the first step in polyol pathway of glucose metabolism.
