The main pathway of galactose metabolism is the Leloir pathway; humans and other species, however, have been noted to contain several alternate pathways, such as the De Ley Doudoroff Pathway. The Leloir pathway consists of the latter stage of a two-part process that converts β-D-galactose to UDP-glucose. The initial stage is the conversion of ...

l-Glucose is an organic compound with formula C 6 H 12 O 6 or O=CH[CH(OH)] 5 H, specifically one of the aldohexose monosaccharides. As the l-isomer of glucose, it is the enantiomer of the more common d-glucose. l-Glucose does not occur naturally in living organisms, but can be synthesized in the laboratory.

Most monosaccharides have the formula (CH 2 O) x (though not all molecules with this formula are monosaccharides). Examples of monosaccharides include glucose (dextrose), fructose (levulose), and galactose. Monosaccharides are the building blocks of disaccharides (such as sucrose, lactose and maltose) and polysaccharides (such as cellulose and ...
Whereas molecular weight (molar mass) for D-glucose monohydrate is 198.17 g/mol, [49] [50] that for anhydrous D-glucose is 180.16 g/mol [51] [52] [53] The density of these two forms of glucose is also different. [specify] In terms of chemical structure, glucose is a monosaccharide, that is, a simple sugar.
In chemistry, a Haworth projection is a common way of writing a structural formula to represent the cyclic structure of monosaccharides with a simple three-dimensional perspective. A Haworth projection approximates the shapes of the actual molecules better for furanoses —which are in reality nearly planar—than for pyranoses that exist in ...
The β-D-methyl glycoside of glucuronic acid in the low energy 4 C 1 conformation of D-glucose. Glucuronic acid is a sugar acid derived from glucose, [2] with its sixth carbon atom oxidized to a carboxylic acid. In living beings, this primary oxidation occurs with UDP-α-D-glucose (UDPG), not with the free sugar.
