What is ‘denaturing a protein’?. Denature: To change the natural qualities of something by chemical or physical means.
Denature: To change the natural qualities of something by chemical or physical means.
Protein: Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes. *
Performance Task Review *
Any of a large number of compounds found in living cells that contain carbon, oxygen, hydrogen, and nitrogen, and join together to form proteins. Twenty of the naturally occurring amino acids are the building blocks of proteins, which they form by being connected to each other in chains. Eight of those twenty, called essential amino acids, cannot be synthesized in the cells of humans and must be consumed as part of the diet. The remaining twelve are nonessential amino acids.
Initial observations and predictions (what do you expect to happen – make a hypothesis and describe the set up of your experiment – what are you going to do)
Add hydrogen peroxide to fresh liver & make observations.
Do same for cooked liver.
Describe and Compare your observations.
Analysis: Explain if denaturation of the protein in liver occurred and if so, how do you know?
