Abstract
Enzymes are catalysts of biological systems, and most enzymes are proteins in nature. They increase the rate of reaction and decrease the energy of activation of a reaction to speed up the reaction. They are specific for substrates and products and function within a moderate pH and temperature range.
Many human diseases result from a mutation in enzymes and enzymes are used as important diagnostic tools and therapeutic targets in a number of diseases.
