Origin of xylose¹

1890–95; < Greek xýl ( on ) wood + -ose ²

The wound gums, for example, yield arabinose, and the wood gums yield xylose.

The product of hydrolysis appears, therefore, to be xylose or a closely related derivative.

All attempts to obtain a crystallisation of xylose from the solution neutralised (BaCO3), filtered, and evaporated, failed.

They have found it possible to work up the corn cobs into glucose and xylose by heating with acid.

But glucose can be more cheaply obtained from other starchy or woody materials and they cannot find a market for the xylose.
