Document Summary
The simplest carbohydrates are monosaccharides, six carbon sugars in a five or six sided ring. Most important role of the carbohydrate is fuel. Basic units that plants string together to create more complex carbohydrates. Six sided ring with an oxygen atom at one apex, two carbons and the remaining oxygen outside the ring. Found in fruits, honey, sweet corn, supplies energy to the body. Very similar to glucose, but slightly different arrangement. Part of lactose, the double sugar found in milk. Double sugars, occur when two monosaccharides are joined together by a chemical bond. When you put two monosaccharides together, you get a disaccharide. Most comes from sugar cane and sugar beets. Also occurs in fruit, honey and maple syrup. Made up of two monosaccharides- glucose and fructose. Yeast can ferment this sugar to provide the alcohol in beer. Only carbohydrate found in significant amounts in any food of animal origin. Lactase is produced by cells in the small intestine.
