  • n. A sirupy variety of sugar, rarely obtained crystallized, occurring widely in honey, ripe fruits, etc., and hence called also fruit sugar; also called fructose. Chemical formula: C6H12O6. It is called levulose, because it rotates the plane of polarization of light to the left, in contrast to dextrose, the other product of the hydrolysis of sucrose.
