Monosaccharide Notation - Trivial Names

Trivial names exist for various frequently occurring modified monosaccharides. For example, 6-deoxy-Galactose is called Fucose (Fuc), or D-glycero-D-3,5-dideoxy-5-amino-galactoNonulonic acid is referred to as Neuraminic acid (Neu). The latter is only defined in D-configuration, i.e. there is no L-Neu. Therefore, "D-Neu" is redundant information, but nevertheless frequently used.

Below there are lists of trivial names used in MonosaccharideDB. Not all of them are supported in all notation schemes. If both a trivial and a systematic name for a monosaccharide are possible in a specific name scheme, the alias list of the respective entry in MonosaccharideDB contains both versions in most cases, with one of them marked as the primary alias.
