They are found in grains, vegetables, fruits, and in milk and other dairy products. The food containing carbohydrates are converted into glucose or blood sugar during the process of digestion by the digestive system. The primary role of carbohydrates is to provide the body with energy, and for the brain and nervous system carbohydrates are the preferred fuel source. In simple carbohydrates, molecules are digested and converted quickly resulting in a rise in the blood sugar levels. The structural organization of monosaccharides is as follows: Monosaccharides may be further classified depending on the number of carbon atoms: (i)Trioses (C3H6O3): These have three carbon atoms per molecule. It is insoluble in water and gives no color with iodine. which contains 3,4,5,6 and 7 carbon atoms respectively.
