One of a class of carbohydrates having from three to nine atoms of carbon in the molecules and having the constitution either of an aldehyde alcohol or of a ketone alcohol. Most glycoses have hydrogen and oxygen present in the proportion to form water, while the number of carbon atoms is usually equal to the number of…
