Euler and Fodor however did not obtain a hexose in this way .
Many of the common heavy metals, when in alkaline solutions, are strongly reduced when boiled with solutions of the hexose sugars.
When hydrolyzed, they yield arabinose and a hexose; the latter is sometimes galactose and sometimes mannose.
These were the hexose constituents of the hydrolysed complex, the pentoses (or 'furfuroids') surviving intact.
On the other hand, Harden and Young regard the acid as a diphosphoric ester of a hexose.
hexose hex·ose (hěk'sōs')
Any of various simple sugars, such as glucose and fructose, that have six carbon atoms per molecule.
