Alex Payne Biology Planning Exercise Denaturation of Egg Albumen Aim: The aim of this experiment is to determine the lowest concentration of copper (II) sulphate solution that brings about full denaturation of egg albumen at room temperature. Biological Knowledge: Egg albumen is a protein that is the make up of egg whites. Proteins are made up of many amino acids in chains. The chains are in very complex arrangements and this determines the function of the protein. The arrangement of the proteins can be separated into four levels: StructurePropertiesPrimaryThis is the chain of amino acids held together by peptide bonds.SecondaryThis is the regularly occurring patterns such as alpha - helixes, held together by hydrogen bonds.TertiaryHow the secondary structure affects the overall shape of the protein.QuaternaryThis is determined by the protein chains. The proteins function is determined by these four structures. When the structure is altered it can either change it's function or it can make the protein ineffective....
