An egg turns white when it is boiled, and a drop of enzyme can break down a whole pan of starch. We study the amino acids and their charges, the peptide bond, the levels of protein structure, denaturation, and how an enzyme speeds up a reaction in chemical terms.

Created by StemPy LabAn egg, a hair and a muscle are mostly protein. Every protein is a chain of amino acids, and the charge of an amino acid changes with the pH. We study the amino acids, the zwitterion and the isoelectric point.
When two amino acids join, they lose a molecule of water and make a peptide bond. This bond is flat and stiff, and it shapes every protein. We follow the chain from its sequence to the folded protein in four levels.
Boil an egg and its clear white turns solid and white. The protein has been denatured. Enzymes are proteins too, and they lose their power in the same way. We look at denaturation, and then at how an enzyme speeds up a reaction in chemical terms.
