Enzymes are proteins, composed of amino acids, produced by the human body and by all animals and plants. Enzymes are catalysts that either begin or cause a reaction to speed up. Enzymes are ferments; they help our bodies break down foods. They are at work in any fermentation process and during the metabolic process. Enzymes cause biological reactions in the body without themselves being changed and are able to be used over and over again. Unlike vitamins and minerals, enzymes are not destroyed as they work.
Enzymes are all around using every animal and every plant. In fact, every living thing needs enzymes in order to function. All living things are run and governed by chemical reactions. In the human body, enzymes are the components that catalyze (or kick start) the chemical reactions that are involved in breathing, digestion, growth, reproduction, blood coagulation, healing, combating disease and everything else that goes on.
