The hydrazones of the common sugars, with the exception of the one from mannose, are colorless compounds, easily soluble in water.
The osones from glucose, mannose, and fructose are identical.
It appears to be resolved by ultimate hydrolysis into dextrose and mannose.
Mannan bears the same relation to mannose that starch does to glucose and inulin to fructose.
The process is reversible; mannose can be converted to mannonic acid, thence to gluconic acid, thence to glucose.
mannose man·nose (mān'ōs')
A monosaccharide obtained from various plants by the oxidation of mannitol.
