Webster's Revised Unabridged Dictionary
    • n Levulose (Chem) 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.☞ It is obtained, together with an equal quantity of dextrose, by the inversion of ordinary cane or beet sugar, and hence, as being an ingredient of invert sugar, is often so called. It is fermentable, nearly as sweet as cane sugar, and is metameric with dextrose. Cf. Dextrose.

Century Dictionary and Cyclopedia
    • n levulose A sugar (C6H12O6) isomeric with dextrose, but distinguished from it by turning the plane of polarization to the left. It occurs associated with dextrose in honey, in many fruits, and in other vegetable tissues. The mixture of these two sugars in equal quantities constitutes invert-sugar, which itself turns the plane of polarization to the left, the specific rotatory power of levulose being greater than that of dextrose. It is usually a thick syrup, having a taste as sweet as that of cane-sugar; it crystallizes with difficulty. Also called fruit-sugar.
