A pure, crystallized fructose (levulose), CH_{2}OH·CHOH·CHOH.
CHOH·CO·CH_{2}OH = C_{6}H_{12}O_{6}, absolutely free from dextrose
(ordinary glucose).
Actions and Uses.—Levulose is metabolized in the body by other agencies
than those that act on dextrose and most of the other sugars and appears
to be more completely utilized by the diabetic organism than the other
sugars. It is recommended for the nutrition and for sweetening the food
and drink of diabetics, in pulmonary tuberculosis, infantile
malnutrition and marasmus. Dosage:—It is given in diabetes in daily
quantities of 30 to 60 grammes (1 to 2 ounces); in grave forms of the
disease the amount is reduced to from 12 to 24 grammes (3 to 6 drachms)
daily. Manufactured by Chemische Fabrik auf Actien, vorm. E. Schering,
