monosaccharide

 [mon″o-sak´ah-rīd]
a simple sugar; a carbohydrate that cannot be broken down to simpler substances by hydrolysis. Subgroups include the aldoses and the ketoses.

mon·o·sac·cha·ride

(mon'ō-sak'ă-rīd),
A carbohydrate that cannot form any simpler sugar by simple hydrolysis, for example, pentoses, hexoses.
Synonym(s): monose

monosaccharide

/mono·sac·cha·ride/ (mon″o-sak´ah-rīd) a simple sugar, having the general formula CnH2nOn; a carbohydrate that cannot be decomposed by hydrolysis. The two main types are the aldoses and the ketoses.

monosaccharide

(mŏn′ə-săk′ə-rīd′, -rĭd)
n.
Any of several carbohydrates, such as tetroses, pentoses, and hexoses, that cannot be broken down to simpler sugars by hydrolysis. Also called simple sugar.

monosaccharide

[-sak′ərīd]
Etymology: Gk, monos + sakcharon, sugar
a simple carbohydrate consisting of a single basic sugar unit with the general formula Cn(H2O)n, with n ranging from 3 to 8.

monosaccharide

Simple sugar A monomer of a more complex carbohydrate Examples Glucose, fructose, galactose. Cf Disaccharide, Polysaccharide.

mon·o·sac·cha·ride

(mon'ō-sak'ă-rīd)
A carbohydrate that cannot form any simpler sugar by simple hydrolysis; e.g., pentoses, hexoses.

monosaccharide

The simplest form of sugar. Monosaccharides are classified by the number of carbon atoms in the molecule. They may thus be trioses, tetroses, pentoses, hexoses, etc. The commonest monosaccharide in the body is GLUCOSE, which is a hexose, with six carbons.

monosaccharide

a carbohydrate MONOMER, a simple sugar with the formula (CH2O)n, e.g. C6H12 O6 glucose and fructose. See Fig. 224 . Such carbohydrates are generally white, crystalline solids, with a sweet taste, and are usually soluble in water. The carbon chain forming the backbone of such sugars can be of varying lengths. Some monosaccharides contain only three carbons (‘triose’ types such as glyceraldehyde) others contain five carbons (‘pentose’ types such as the deoxyribose sugar of DNA), but those with six carbons (‘hexose’ types such as glucose) are the most important since they can be joined together by CONDENSATION REACTIONS (loss of water) to form DISACCHARIDES and POLYSACCHARIDES.

The antioxidant activity of a polysaccharide depends on its combined structural characteristics, including the configuration of the glycosidic bond, molecular weight, and monosaccharide content (Zheng et al.
In fact, when melibiose, which is a disaccharide having an acid-labile 1,6-glycosidic bond, was treated with methanol in the presence of hydrogen chloride under Fischer's conditions, the product was a mixture of monosaccharide derivatives as a result of glycosidic bond cleavage.
Finally, we investigated the preliminary analysis of monosaccharide composition.
The release of monosaccharides caused by exogenous enzymes is due to two reasons: firstly, the breakdown of NSP led to release of their respective monosaccharides, and secondly, the breakdown of NSP released the starch within the endosperm, which was exposed to the endogenous amylase, releasing more glucose (Malathi and Devegowda, 2001).
But the bovine oligosaccharides lack fucose, a monosaccharide that in human milk adorns up to 70 percent of oligosaccharides, tending to lend them pathogen-blocking powers.

Salacia has salacinol, kotalanol, kotalagenin-16 acetate and mangiferin which help to decrease postprandial glucose and thus slow the carbohydrate breakdown into absorbable monosaccharides.
