Proteins - Essay Example Enzymes can be defined as catalysts that cause a chemical reaction to process at a quicker pace. For instance, oxygen is a catalyst for fire. Enzymes are the catalysts of biological and chemical processes that are related to a variety of natural processes occurring in human beings. This includes a wide range including the formation, decomposition and rearranging of molecules to provide the individual with the energy and essential substances needed to live and function. Without enzymes however, these processes would occur far too slowly for proper metabolism. Enzymes are composed of amino acids. This combination of amino acids is usually referred to as a protein. Many refer to enzymes as special proteins that are biologically active or contain energy. It is because of this energy releasing element that enzymes are able to perform its work. Nevertheless, enzymes cannot be classified alongside other proteins. Once the enzyme no longer possesses energy, it will fail in its function as a catalyst and is now equal to any other general protein in the body. Enzymes are classified under several key groups. These include Proteases that help breakdown proteins, Lipases that help decompose lipids and fats, Amylases that help break down carbohydrates and finally Cellulases that break down the vegetative matter called cellulose. Further enzymes can also be classified as digestive enzymes, food enzymes, metabolism enzymes, etc. Food enzymes are introduced to the body via the oral intake of foods. However, food in this crude form manifests only necessary enzymes to digest that particular food item, which is usually not sufficient for storing in the body for use at a later time. It should be added that the process of cooking and processing (as done in mass produced foods) depletes the food of all its enzyme content. In this context, enzyme therapy comes as a boon for all those aspiring to prolong their natural lives. By understanding the core
