Definition - What does Enzymes mean?
Enzymes are naturally forming proteins that are produced in small amounts by all living organisms including bacteria, plants, and animals. These proteins are very selective biochemical catalysts and are capable of converting one kind of molecule into another by catalytic action.
Enzymes are essential to life as they speed up metabolic processes greatly, yet they do not undergo any changes themselves.
Safeopedia explains Enzymes
Enzymes are catalytic in that they produce changes in other materials that they come into contact with without changing at all themselves. They are specific shapes that can interact only with certain substances, so they are selective in the processes that they can influence and they are varied. They are important for things such as brain stimulation, digestion, providing cellular energy, repairing tissue, organs and cells, and so on. They are also used outside the body in industry for various chemical purposes.
