The two main categories of sugars are monosaccharides and disaccharides. They are often described together with polysaccharides, and sometimes also oligosaccarides, due to the chemical relationship between these types of carbohydrates: 1  Categories of sugars 2  : Monosaccharides are simple (unit) sugars.3  Disaccharides consist of molecules whose form is that of.here are several types of sugar. This page mentions some specific sugars but concentrates on the main categories of sugars (monosaccharides and disaccharides) and the relationship between these and certain larger carbohydrates. Definition of sugar : A sugar is a carbohydrate that is soluble in water.
