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 2x ...
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Monosaccharides are also called "simple sugars", the most important being glucose. Most monosaccharides have a formula that conforms to C n H 2n O n with n between 3 and 7 (deoxyribose being an exception). Glucose has the molecular formula C 6 H 12 O 6. The names of typical sugars end with -ose, as in "glucose" and "fructose".
A glycosidic bond or glycosidic linkage is a type of ether bond that joins a carbohydrate (sugar) molecule to another group, which may or may not be another carbohydrate. Formation of ethyl glucoside: Glucose and ethanol combine to form ethyl glucoside and water .
The CDC reports that approximately 1 in 10 Americans has diabetes — a medical condition that affects sugar levels in your blood, as well as other related functions your body performs.
Polysaccharides, meanwhile, have a general formula of C x (H 2 O) y where x and y are usually large numbers between 200 and 2500. When the repeating units in the polymer backbone are six-carbon monosaccharides, as is often the case, the general formula simplifies to (C 6 H 10 O 5) n, where typically 40 ≤ n ≤ 3000.
Fischer projection of D-glyceraldehyde. Like most carbohydrates, simple aldoses have the general chemical formula C n (H 2 O) n.Because formaldehyde (n=1) and glycolaldehyde (n=2) are not generally considered to be carbohydrates, [1] the simplest possible aldose is the triose glyceraldehyde, which only contains three carbon atoms.
The anomeric effect can also be generalized to any cyclohexyl or linear system with the general formula C−Y−C−X, where Y is a heteroatom with one or more lone pairs, and X is an electronegative atom or group. [3] The magnitude of the anomeric effect is estimated at 4-8 kJ/mol in the case of sugars, but is different for every molecule.
