'The aim of this experiment was to investigate whether or not certain foods contained the different food groups\r'

' rear †The aim of this experiment was to investigate whether or not certain feeds compriseed the polar nutriment groups. If it saturnine corrosive that meant it had starch, if it turned departure that meant it had glucose, if it turned purple it meant it had protein and if it turned clear/transpargonnt it had fat.\r\nThe equipment employ was vegetable oil, pallet, pipette, starch, glucose, albumin, one solution, and Benedict’s solution and copper sulfate solution. The method was simple, mixing each(prenominal) type of forage with the intellectual nourishment group to see if it would change burnish and if it contained this food for thought group, for example if iodine was added to starch and its colorize changed it pass on have contained iodine in it.\r\n origin †All the processes of life require energy, and this energy comes from food groups. Carbohydrates provide energy for movement and this is do up of carbon, hydrogen and sugar. It is found in cereals and pasta. Proteins are used to assist growth and repair for the embody it is made up of amino acids and is found in eye and fish. Fats are used to provide a strong source of energy and to insulate the body in cold temperatures. Saturated fats are obtained from animals such as meat; stock-still polyunsaturated fat comes from vegetables.\r\nVitamins are necessary in small amounts for growth however incompatible vitamins have different functions; vitamin A is compulsory to give good vision and it is from vegetables such as carrots. Vitamin B releases energy from food and it is obtained from milk and bread. Vitamin C gives healthy skin and this is from oranges and other fruits. Vitamin D helps to operate calcium and this comes from margarine and oily fish.\r\nThe compilingive dodge has two main functions, one of them is to convert food into nutrients in what the body requires, the other functions is to remove some(prenominal) waste which may be in the body.\r\nmethod acting †Starch test: First collect the food sample (liquid) and add a few drops of iodine solution ( chickenhearted/brown) and thus check if the coloration changes from yellow/brown to risque black ink because it will contain starch.\r\nFat test: We collected the food sample and we put it on a piece of paper and if it went through it contains fat.\r\nProtein test: later on we collected the food samples which were liquid in a test resistance and added 5 drops of copper sulphate and 5 drops of sodium hydroxide and if the colour changes from blue to purple thusly(prenominal) the food sample does contain protein.\r\nSugar : First collect the food samples in a test tube and add a few drops of benedicts solution. Then place the test tube in a boiling water bath. If the colour changes from blue to green and then to orange to red the sample contains sugar. The colour changes depending on the concentration of the sample.\r\n(P6) The body requires all the nutrients to remain hea lthy however different people will regard a different variety and portion size compared to others, for example athletes will requirement a high diet in carbohydrates and meat because they need it to release energy and beef up their bones more than an office worker would need it, however an office worker will need a lot of vitamin A because it spends its time on the computer working and this can damage their eyes.\r\nIf a somebody ate too oftentimes of the food groups then that individual will have perplex over nourish and if that isn’t worked off then the body will become fatter and overweight, too much fatty foods and oils cause this.\r\nHowever if a person ate too less of the food groups then that person will become under nourished which means that the body will become faithful and underweight. This is caused due to a lack of diet.\r\nIf a person ate too less of vitamin A then the eyes will have problems seeing at night however if it was too less vitamin C then the m outh will become change and it will develop scurvy.\r\nThe body has different enzymes which digest the different food groups †Protease is the enzyme which attains to the equipment failure of protein, Lipase is the enzyme which attains to the breakdown of fat and amylase is the enzyme which attains to the breakdown of starch.\r\nMethod †Mixing each of the food groups into the different test such as iodine test to see if it has this substance in it.\r\nOther enzymes such as Maltase digests maltose to glucose, lactase digests lactose to glucose and galactose, Sucrose digests sucrose to glucose and fructose.\r\n'
