<P> Generally , Benedict 's test detects the presence of aldehydes and alpha - hydroxy - ketones , also by hemiacetal , including those that occur in certain ketoses . Thus , although the ketose fructose is not strictly a reducing sugar , it is an alpha - hydroxy - ketone , and gives a positive test because it is converted to the aldoses glucose and mannose by the base in the reagent . </P>
