Carbohydrate

Carbohydrate
The carbohydrate is organic compound composed of carbon, hydrogen, oxygen three kinds of elements, also call it the carbohydrate. The nutrient of carbohydrate can be divided into three kinds monosaccharide, disaccharose and many candies. The monosaccharide includes glucose, fructose and galactose, it is the base unit which makes up disaccharose and many candies, it is the basic form that the nutrient of carbohydrate digests and assimilates in the food. Disaccharose is cane sugar, malt sugar and lactose, among them the cane sugar was condensed by a molecule glucose and a molecule fructose, white sugar eaten, brown sugar belong to this kind of carbohydrate, it is relatively high with content such as the sugarcane, beet beetroot in the natural food; The malt sugar was condensed by two molecule glucose, the content was the most abundant in the valley bud, especially malt, confirm the degree in beer with the content of malt sugar; Lactose was condensed by a molecule glucose and a molecule galactose, it was the main form of the nutrient of carbohydrate present in the dairy products. Many candies include starch, dextrin, candy yuan, is not waited for the glucose molecule to condense by more than 3 quantity, among them the starch is the main carbohydrate nutrient existing in food of plant such as grain cereal, beans, hard fruits, potatoes, it is a main source of carbohydrate in the human food, the starch is digested in the digestive tract into glucose and absorbed into the blood, glucose in the blood is blood glucose; The dextrin is that the starch decomposes the middle product produced, the content is relatively abundant in the polished glutinous rice; Candy yuan deposit on the intersection of animal and liver,etc. in the organization only, also called hepatin, but because the content is very little, it is not mankind's main source of obtaining carbohydrate. Carbohydrate human the intersection of organism and normal physiology move about, grow and main the intersection of heat energy and source at the physical exertion, especially main energy and fuel of the muscule activity of nervous system, heart. If the carbohydrate is taken in insufficiently, blood glucose will drop, can present hypoglycemia syndrome, light and will reduce working efficiency, the heavy function that will influence the brain to organize moves about, because the energy is not enough to collapse, faint from fear, even go into a coma seriously. Thus it is inadvisable that a lot of people do not have breakfast because of various reasons. The carbohydrate is the important composition which forms the cell tissue too at the same time, if glycolipid in the glycoprotein in the glycoprotein in the cell membrane, connective tissue, nerve fiber contains the carbohydrate content. Enough carbohydrate supplies and also saves internal protein to consume; Savings of not complete supersession product acetone body while reducing the fat to excessively decompose, thus prevent acidosis; Still protect the liver detoxication. The main food source of nutrient of carbohydrate is the grain cereal, potato food, secondly also come from a small amount of monosaccharide in edible candy and vegetables, fruit on a small quantity. Carbohydrate the intersection of nutrient and delivery volume make with working property and labour intensity, according to of our country eating habit of people, in order to account for 60%- 70% of the total amount of heat, per kilogram of weight every day of general adult probably takes 4- 6 grams of candy, if the activity intensity is strengthened, then the delivery volume of the candy needs to increase.
