Carbohydrates are classified into three types. They are classified according to the complexity of sugars. These types are the polysaccharides, the disaccharides and the monosaccharide.
The polysaccharides are multiple sugars. These sugars have more than 10 saccharides units. They consist of digestible types. Examples are starch and dextrin. Starch is commonly found in cereal grains, rice and other rice products, bread as well as other flour products. The dextrin on the other hand can be found for example in toasted bread and is the intermediate product in the digestion of starch.
The disaccharides are forms of sugars which are hydrolyzed into 2 simple sugar units. Disaccharides are consists of lactose, maltose, and sucrose.
Sucrose is also known as cane sugar or beet sugar. Sucrose is also found in syrups, molasses, and some are found in some fruits. It can also be used in cooking purposes, it is also known as table sugar.
Maltose is a kind of malt sugar. This sugar is produced from the digestion of starch inside the intestine.
Lactose is also another form of disaccharide also called as milk sugar. It is commonly found in milk and milk products. Lactose is the least sweet among the common sugars.
The monosaccharides are simple sugars. They are consisted with glucose, fructose, and galactose.
Glucose is also called as dextrose or grape sugar. It is commonly found in fruits and honey, they can also be found on sweet corns. Glucose is the end product of starch digestion. It is the sugar form which oxidized by the body in order to release energy. (navteq coupon)
Fructose is considered as sweetest of all sugars. Fructose is commonly found in ripe fruits, vegetables as well as in honey. In the liver and in the intestine, fructose is change into glucose.
Galactose is the sugar that derived from lactose. It changes to glucose to release certain amount of energy.
Carbohydrates functions as a chief source of energy, as a protein sparer and as a fat sparer.
It also regulates the peristaltic movement of the intestine. Carbohydrates functions as a chief source of energy as the glucose became the most readily available source of energy that is needed by the body at the end of the digestion process.
The Carbohydrates also acts as a protein sparer. It means that the presence of the carbohydrates, spare the use of protein for energy use. Hence protein is use for body-building and not use for energy-giving.
It also act as a fat spares thus it prevents the incomplete oxidation of fats. Lastly, carbohydrates, regulates the peristaltic movement of the intestine. The peristaltic movement becomes regular through the presence of carbohydrates together with the presence of cellulose or the indigestible fiber. Through this constipation is prevented and regular bowel movement is established.
