Although corn is the main source of sugars for the production of ethanol, it is not the only one. Ethanol is produced from simple six to twelve carbon sugars derived from carbohydrates, the sources of which belong to three different feed stocks. The first being saccharides, which are harvested from sugar cane, sugar beets, fruits, and citrus molasses. These sources require no purification for the production of ethanol. The second source of sugar comes from starchy materials, which require some processing to access the sugar molecules vital to the process. Crops that are classified as starchy materials are; corn, potatoes, barley, and wheat. The last class of materials that can be used in the ethanol process are cellulose materials. This class includes; wood, wood waste, paper, straw, grasses, corn stalks, corn cobs, and
