Simple monosaccharides have a linear and unbranched carbon skeleton with one carbonyl (C=O) functional group, and one hydroxyl (OH) group on each of the remaining carbon atoms. Therefore, the molecular structure of a simple monosaccharide can be written as H(CHOH) n (C=O)(CHOH) m H, where n + 1 + m = x ; so that its elemental formula is C x H 2 ...

Sweet-tasting, water-soluble carbohydrates This article is about the class of sweet-flavored substances used as food. For common table sugar, see Sucrose. For other uses, see Sugar (disambiguation). Sugars (clockwise from top-left): white refined, unrefined, unprocessed cane, brown Sugar ...
Free sugar – all monosaccharides and disaccharides added to food and naturally present sugars in honey, syrups, and fruit juices (sugars inside cells, as in raw fruit, are not included) Fructose [1] – a simple ketonic monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose
If the carbonyl group is an aldehyde, the monosaccharide is an aldose; if the carbonyl group is a ketone, the monosaccharide is a ketose. Monosaccharides with three carbon atoms are called trioses, those with four are called tetroses, five are called pentoses, six are hexoses, and so on. [16] These two systems of classification are often combined.
Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form. Glucose is naturally occurring and is found in its free state in fruits and other parts of plants.
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.
In general, only one of the two enantiomers occurs naturally (for example, D-glucose) and can be metabolized by animals or fermented by yeasts. The term "hexose" sometimes is assumed to include deoxyhexoses , such as fucose and rhamnose : compounds with general formula C 6 H 12 O 6− y that can be described as derived from hexoses by ...
D-Glyceraldehyde is an aldotriose because the carbonyl group is at the end of the chain Dihydroxyacetone is a ketotriose because the carbonyl group is the center of the chain.. A triose is a monosaccharide, or simple sugar, containing three carbon atoms.
