Like all other proteins, enzymes are made of amino acids. Each enzyme is made of between a hundred and upwards of a million amino acids placed like pearls on a string. Each amino acid is bonded to the next by chemical bonds.The vast majority of enzymes are made of only 20 different kinds of amino acid.nzymes break down your food. Enzymes are the workhorses of the body. When you eat, enzymes break down the food into tiny particles which can be converted into energy in the body. The process starts in the mouth, where an enzyme called amylase attacks all incoming food particles.
In this lab, you will study an enzyme that is found in the cells of many living tissues. The name of the enzyme is catalase (KAT-uh-LAYSS); it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen.hey do not die because your cells use enzymes to break down these poisonous chemicals into harmless substances. Enzymes are proteins that speed up the rate of reactions that would otherwise happen more slowly. The enzyme is not altered by the reaction.
