Lab Report Identifying Food Groups
ups Identifying food groups in unknown solutions
Aim
The aim of this experiment is to identify different food groups within several different unknown solutions. This will be carried out by placing the unknown solutions into separate test tubes and using different chemical indicators to see if any reactions occur. Each food group will act different when the chemical indicator is added, some will change colour while others will separate.
Introduction
Food is a vital source of energy that is needed for survival, without this energy source our bodies wouldn’t be able to function. All food can be broken down into various food groups such as water, proteins, carbohydrates, vitamins, fats, fibre and minerals. Our bodies need all of these food groups to function with each of them playing a specific role. These food groups are present in our every day food and are taken into our body through a process of digestion. The food is chewed up and broken down into smaller bits in the mouth and then travels down to the stomach where it is broken down further by the hydrochloric acid in the stomach in a process called chemical digestion. Once the food has been broken down it is then absorbed by the blood to provide the various functions that our body needs to survive. We can get some of these food groups by other means such as vitamin injections, tablets …show more content…
Each protein is made up of a linear chain of amino acids linked together by peptide bonds (all peptide bonds are covalent bonds). The amount of amino acids bonded together can vary from tens too thousands, creating different proteins. There are 20 different amino acids in living organisms and the combination of these amino acids linked together in different polypeptide chains can result in trillions of different combinations of chains creating many different proteins (proteincrystallography,
