  Monosaccharide - Wikipedia, the free encyclopedia
Monosaccharides are the building blocks of disaccharides like sucrose (common sugar) and polysaccharides (such as cellulose and starch).
Monosaccharides contain either a ketone or aldehyde functional group, and hydroxyl groups on most or all of the non-carbonyl carbon atoms.

 Carbohydrate : w8pedia   (Site not responding. Last check: 2007-11-05)
The simplest carbohydrates are monosaccharides, which are small straight-chain aldehydes and ketones with many hydroxyl groups added, usually one on each carbon except the functional group.
Monosaccharides may be divided into aldoses, which have an aldehyde group on the first carbon atom, and ketoses, which typically have a ketone group on the second.
Oligosaccharides and polysaccharides are composed of longer chains of monosaccharide units bound together by glycosidic bonds.

 Monosaccharide
In addition, carbon atoms that support hydroxyl groups allow isomers of monosaccharides; galactose and glucose both are aldohexoses, but isomers; each has very different properties chemically and physically.
When n or m is zero, the monosaccharide is an aldose; when they are not zero, it is a ketose.
Monosaccharides are often classified by the number of carbon atoms they contain: Monose, Diose, Triose, Tetrose, Pentose, Hexose, Heptose, Octose, and Nonose are the first nine monosaccharides.

A monosaccharide is a carbohydrate that cannot be hydrolyzed into a simpler unit.
Ring forms of the monosaccharides are the rule in oligosaccharides, which are branched or linear chains of monosaccharides attached to one another via glycosidic linkages (the term polysaccharide is typically reserved for large glycans that are composed of repeating oligosaccharide motifs).
Monosaccharides are the basic structural units of glycans.

It would be nice if your monosaccharide tool would return an additional XML element or attribute that specifies the name of the monosaccharide that would be released by hydrolysis of the glycan, as I just described.
In my opinion, substituents are part of the monosaccharide, especially as some of them replace a part of the stem monosaccharide (the hydroxyl group) and/or significantly modify the properties of the monosaccharide moiety, e.g.

 Monosaccharide DB - Rules for residue notation
For an efficient handling of carbohydrate structures in databases and computer software, a unique nomenclature for the monosaccharide units is indispensable.
Without a normalisation of monosaccharide residue notation, it is not only difficult to cross-link carbohydrate databases but even possible that one structure is represented by two or more entries within one single database.
Therefore, we moot some rules, which monosaccharide nomenclature should follow.

 (WO/1989/007591) CONTROL OF PRODUCT SELECTIVITY IN THE ADDITION OF HCN TO ARABINOSE   (Site not responding. Last check: 2007-11-05)
(EN) Hydrogen cyanide addition to a monosaccharide results in a mixture of product cyanohydrins whose ratio can be changed by conducting the hydrogen cyanide addition in the presence of an agent which forms a complex with the monosaccharide.
It is preferred to add the elements of hydrogen cyanide to a preformed complex of the monosaccharide.
The product selectivity appears to be dependent upon the concentration of the complexing agent up to about one molar proportion of the latter relative to the monosaccharide with the selectivity being invariant thereafter.

Further, each carbon atom that supports a hydroxyl group is optically active, allowing a number of different carbohydrates with the same basic structure.
For instance, galactose is an aldohexose but has different properties from glucose because the atoms are arranged differently.The straight-chain structure described here is only one of the forms a monosaccharide may take.
