Enzymes are primarily protein molecules that consist of amino acids. They act as biological catalysts responsible for all the biochemical reactions taking place in our body that control life's processes. Enzymes are essential for life sustenance and cellular activity. Life is not possible without enzyme. The amount of enzymatic activity in the body is the indicator that determines "sickness and health".
Generally, the human body consists of 70% water, 15% protein, 13% fat and numerous enzymes responsible for various chemical changes in the body. There are more than 3,000 enzymes in our body to keep us in good health. Anything from digestion of food, limb movement, thinking, the changes happpen 24 hours a day without stopping.
Among our nutrient intake, carbohydrate from grains, glycogen contained in meat and animal livers, lactose from milk and fructose from fruits, etc, also are our energy sources.
Without enzymes, it would be impossible to digest, absorb and utilise these nutrients. Without enzymes in the body, we would not be able to absorb any nutrients.
Enzymes are also crucial for the reactions of each organ in the body. For example, enzymes digest the food so that food is small enough to pass through the cellular membrane of the small intestines and into the blood. Enzymes in the blood will in turn build muscles, nerves, blood and glands from the fully digested nutrients.
Meanwhile, enzymatic actions will also enable carbohydrates to be stored in liver and muscles as well as converting fat into fatty tissues.
Enzymes also aid the formation of urea so that the latter will be excreted in the urine. One particular type of enzyme even aids the bone and nervous tissue in absorbing phosphorus and another enzyme aids the red blood cells in iron absorption.
Hence, enzyme plays an extremely important role in the propagation of life. Enzymes in the immune system clear and eliminate foreign bodies and toxins in the blood tissues.
