<P> With few exceptions ( e.g. , deoxyribose ) , monosaccharide have this chemical formula : C ( H O ) , where conventionally x ≥ 3 . Monosaccharides can be classified by the number x of carbon atoms they contain : triose ( 3 ) , tetrose ( 4 ) , pentose ( 5 ) , hexose ( 6 ) , heptose ( 7 ) , and so on . </P>
