What is monosaccharide
Single sugars (Monosaccharide): no longer hydrolysis more simple sugars, according to the number of carbon atoms can be divided into three-carbon sugar, four-carbon sugar, five-carbon sugar, six carbon sugar, carbon sugar seven or eight carbon sugar.

Glucose: from starch, sugar maltose and lactose hydrolyzate is used by organizations as a major sugar. High blood sugar in diabetic patients in the urine will be measured by high concentration of sugar, and commonly known as diabetes.
What is meant by disaccharides
Two-carbohydrate (Disaccharide): refers to hydrolysis can be produced after the Second elements the same or different monosaccharides, such as sugar (sucrose), lactose (lactose) and maltose (maltose).

Maltose (maltose): starch water product, is the germination of grains and malt.
Lactose (lactose): milk, urine during pregnancy may have. Sugar (sucrose): sugar cane and beet sugar, pineapple plants Sorghum carrot root.
Fine seaweed (trehalose): mushrooms and yeast, is the insect hemolymph of the main carbohydrate.
What is polysaccharide
Polysaccharides (Polysaccharide): can be produced by the hydrolysis of at least 6 monosaccharide molecules, and it may be straight-chain or a branched-chain. Included;

a) starch (starch): After its hydrolysis produced only glucose, there is a polymer with the starch found in grains, MA Ling potato, it is the most important source of carbohydrates, the main two forms were Melosira starch (accounting for 15-20%) and amylopectin (80-85%), from glucose to α \ (1 → 4) α \ (1 → 6) linked the two keys sugar.
b) Glycogen: It is the storage of animal polysaccharides, it often referred to as animal starch, from α \ (1 → 4) α \ (1 → 6) linked the two keys sugar.
c) Cellulose: It is the main component of plant skeleton, by β (1 → 4) indirect form long straight chains, including humans Xu \ more mammals lack the enzyme hydrolysis bond, it can not digest cellulose. In ruminants and other herbivores are biodegradable intestinal microbes exist, can make use of cellulose to become a major source of energy.

Sweeteners: aspartame (Aspartame) is the day Mendong acid and phenylalanine posed by artificial sweeteners. Its sweetness is 200 times that of sugar, is safe, easily absorbed the advantages of low-calorie. Apply to dental caries, diabetes and obesity patients
