[Gk. glykys, sweet] or Grape Sugar. A kind of sugar found in grapes, less sweet than cane sugar. In the United States it is chiefly prepared from corn starch, where the syrup is known commercially as glucose, and the solid product from the same source as starch sugar. In Europe it is made from potatoes. Glucose is used chiefly in the preparation of table syrups and confectionery, in brewing, in the preparation of artificial honey, and as food for bees.
