* All carbohydrates are made up as NUTRIENTS RATIO * Carbon * Hydrogen 1:2:1 * Oxygen * There are three main types of carbohydrates these are * Sugar * Starches * Non - starch polysaccharides (fiber) Reference: http://www.thefitmap.co.uk/nutrition/macronutrients/carbohydrates/index.htm Website viewed on 25 / 6 / 08 > Biological Functions of Carbohydrates * The main reason for sugar and starch is to actually provide energy for the body however once they are broken up into monosaccharide they might be either * Delivered to all the cells of they body so that they can be used straight away for energy through a process called respiration. * Converted into glycogen and stored within the liver and muscles as readily available source of energy. * Converted into fatty acids and then stored in the adipose tissue as a source of energy. * Fiber is important to functioning the digestive system because the different goods of the fiber tends to actually affect their biological function within the body however if the fiber is taken is excess then this can lead to reducing the absorption of some minerals. * Monosaccharide are water soluble and they very in sweetness however their tastes can be modified therefore this are done by cooking for example glucose, fructose and glactose. * Another name for glucose is (dextrose) this accurse naturally within:- * Fruits * Plant juices * In the blood of the living animal, * Most carbohydrates in our foods are converted to glucose during digestion however within the food industry glucose is processed from starch by the actions of the acids and enzymes; therefore it is then used in confectionary, soft drinks and also jams. * Galactose is naturally found within the milk, this also includes human breast milk. Reference http://en.wikipedia.org/wiki/Biochemistry#Carbohydrates_2 Website viewed on 26 / 6 / 08 > Disaccharides * Disaccharides is two monosaccharide linked together. * Disaccharides normally relates to two sugars, however this is similar to monosaccharide. ...read more.

Conclusion

Chemical reactions which take place within the body produce and make water; this is used in the body as a main solvent in which chemical reactions take place this is because it is used to help with digestion and to get rid of all the waste, water is also used for transporting and passing substances around the body. Water is part of your immune system which helps to fight illnesses and diseases because the water is an important part of all the fluids in your body; each individual cell tends to depend on water in order to function properly. The kidney carefully controls and adjusts the balance of water this is when the kidney and the brain controls the amount of water sent out by the body for example when the blood volume is low, and then the concentration of solutes within the blood is high. The brain tends to react to this matter by motivating the pituitary gland to actually release the ADH which stands for anti- diuretic hormones, this then signals the kidney to reabsorb re-circulate the water. The water intoxication occurs when there is an excess amount of fluids within the body, the excess fluids may collect within the muscles particularly within the legs and feet this is called the edema. The system of water intoxication are convulsion, confusion and it can also lead to death however it is recommended that an adult should drink up to eight to ten units of water a day and children should drink up to eight to twelve units of water a day, this is because when the body is loosing water constantly, the concentration of solutes within the blood tends to become too high, therefore the solutes attracts the water from the salivary gland which then makes the mouth dry, this then courses the person to feel thirsty.
