sugar belonging to the glucose group, 1867, shortened from dextro-glucose, from dextro- "right" + -ose (2), chemical suffix indicating a sugar. So called because this form of glucose polarizes light to the right in spectroscopy.
standard ending in chemical names of sugars, originally simply a noun-forming suffix, taken up by French chemists mid-19c.; it has no etymological connection with sugar. It appears around the same time in two chemical names, cellulose, which would owe it to the French suffix, and glucose, where it would be a natural result from the Greek original. Flood favors origin from glucose.
