Diose

A diose is a monosaccharide containing two carbon atoms. Because the general chemical formula of an unmodified monosaccharide is (C·HO), where n is three or greater, it does not meet the formal definition of a monosaccharide. However, since it does fit the formula (C·HO), it is sometimes thought of as the most basic sugar.

The large number of sugars prepared synthetically, some of which have not yet been found in nature, together with the natural sugars are subdivided into groups. We distinguish, in the first place, between the more simple sugars called monosaccharides and compound sugars called polysaccharides. The latter may be regarded as formed from two or more molecules of the former with elimination of water, and, as a matter of fact, the simpler sugars may be formed from them by hydrolysis.
The monosaccharides again are divided into subclasses governed by the number of carbon atoms in the molecule. Thus we have a diose (glycol aldehyde, or glycolose, HC(O)-CHOH) which is the simplest possible sugar, and trioses, tetroses, pentoses, hexoses, heptoses, etc.

There is only one possible diose, glycolaldehyde (2-hydroxyethanal), which is an aldodiose (a ketodiose is not possible since there are only two carbons).

Usage examples of "diose".

Most members of die Institute of Genetic Art preferred to exhibit dieir work pseudonymously in diose days-a hangover from the era when there were too many people still alive who associated genetic engineers widi the weapons errf-ployed in the plague wars and the chiasmatic transformers which caused the Crash.

Our soldiers have pumped salt water into men to make them talk, and have taken prisoners people who held up their hands and peacefully surrendered, and an hour later, without an atom of evidence to show that diey were even insurrectos, stood them on a bridge and shot them down one by one, to drop into the water below and float down, as examples to diose who found their bullet-loaded corpses.

People no longer telt the same obligation to obey diose whom they had previously considered superior to themselves in age, rank, status, expertise, character, or talents.
