The Sugar-Beet in America 



of flowers. It exists in solution in the cells of plants. 

 Dextrose and levulose, which usually occur together, are 

 found in most fruits, in honey, and in many other products. 

 Honey consists of a natural mixture of about 37 per cent 

 each of dextrose and levulose, and may contain as high as 

 6 or 8 per cent of sucrose. Milk-sugar, or lactose, is con- 

 tained in milk, from 4 to 5 per cent being present. iMalt- 

 sugar, or maltose, results from the action of diastase on 

 starchy materials.
