What is the carbohydrate
First, brief introduction of carbohydrate
The carbohydrate also calls the carbohydrate compound, it is the nature that exists at most, distributes the widest kind of important organic compound. Glucose, cane sugar, starch and cellulose,etc. are the carbohydrate compound.
The carbohydrate compound is a main source of the energy involved in maintaining life activity of all organism. Its not only nutriment, but also some have special physiological activity. For example: Heparin in the liver resists the function of blood coagulation; The candy in blood group relates to immune activity. In addition, contain the carbohydrate compound in the composition composition of the nuclear acid - -Ribose and deoxyribose. So, the carbohydrate compound has more important meanings for medical science.
The nature exists most, organic compound with wide table chemical constitution and biological function. Mainly consist of carbon, hydrogen, oxygen. Available formula Cx(H2O) It is expressed that y comes. Have monosaccharide, liogosaccharide, starch, half cellulose, cellulose, compound many candies, and derivative of the candy. But forming mainly by the green plants through the photosynthesis, it is the initial product of the photosynthesis. By the look of chemical constitution characteristic, it with aldehyde oves many hydroxyls or ketone compound or hydrolyze, transform, become many the intersection of hydroxyl and aldehyde or compound of ketone type. Such as glucose, contain a aldehyde base, six carbon atoms, call aldohexose. Fructose contains a ketone base, six carbon atoms, call own ketose. It, protein, fat are all the three basic materials of living nature, for the growth, sport, breeding and offering the main energy of the living beings. It is one of the essential important materials of human survival and development.
Carbohydrate divide monosaccharide, biose, low to gather candy, many the intersection of candy and 4 into. The combination of the candy is three kinds glycolipid, glycoprotein, protein polysaccharide.
Second, Japan's recommendation amount and food source
Generally speaking, do not have particular diet that is required to the carbohydrate. Should mainly take in from the heat of obtaining the rational proportion in the carbohydrate. In addition, should take in 50- 100 grams at least and can be digested (digest the food) every day Carbohydrate Israel prevent carbohydrate deficiency disease.
The main food source of the carbohydrate is as follows, cane sugar, grain ( For instance rice, wheat, corn, barley, oat, Chinese sorghum,etc.) , fruit ( For instance sugarcane, muskmelon, water-melon, banana, grape,etc.) , nut, vegetables ( For instance the carrot, sweet potato,etc.) When.
