What Is An Enzyme

Enzymes are considered the missing link in health rebuilding as they hold the key to a better health. Although every element in your body plays an important role for the smooth running of the body, enzymes are actually vital and involved in almost all the chemical reactions that take place in the body hence they are regarded as the link that enables other elements to work efficiently.

what is an enzyme


So then, what is an enzyme? Enzymes are body catalysts that speed up a chemical reaction. As body catalyst, they speed up the biochemical reaction that would otherwise proceed at a much slower rate, if it would proceed at all. They are the macromolecular biological catalyst and just as the definition goes, they are responsible for almost all chemical reaction in the cell.They set the stage for almost all metabolic activities that take place in the body.

Every Cell of the body has some enzymes. Studies have it that every cell has as many as 1000 enzymes that carry out various catalytic activities within. About two million biochemical reactions take place through out the body every moment that requires the use of enzymes for motility and a deficiency of any one enzyme can create nutritional upheaval to weaken and break the chain of interrelated health


Types Of Enzymes.

Based on what they catalyze, enzymes can be group into six and they are as follows.

  • Transferase
  • Ligase
  • Oxidoreductase
  • Isomerase
  • Hydrolase
  • Lyase

Each of the listed group of enzymes here carries out at a given time its duty of accelerating chemical reactions at rates fast enough to sustain life and all without altering the equilibrium of a reaction.

Most enzymes are known to be proteins but a selected few are catalytic RNA molecules. Studies reviewed that more than 5,000 biochemical reaction types are catalyzed by enzymes all through the body.


Types Of Enzymes In Human Body.

The human body is thought to have an astonishing 75,000 enzymes all of which are divided into three major groups.

what is an enzyme

  • metabolic enzymes.
  • digestive enzymes.
  • food enzymes.

Out of the three types of enzymes in a human body, both metabolic and Digestive enzymes are produced by the human body, however, Food enzymes must come from plant foods as our bodies do not produce this kind of enzyme.


Metabolic Enzyme.

These are enzymes produced by the human body and they are responsible for all metabolic activities in the human body such as energy production level, detoxification, the growth of new cells, repair and maintenance of damaged organs and tissues and all sorts of metabolism that takes place in the human body. They are also involved in the sensory system.


Digestive Metabolism.

The digestive process of the intestinal tract is those that perform the finishing touches and final preparations before nutrients can be absorbed. The primary factors in these processes are biochemicals known as enzymes.

For intestinal digestion, special cells in the pancreas manufacture enzymes from amino acids and secrete them into chyme(partially digested food from the stomach); here, they catalyze the reactions that break our food down further and free the nutrients they contain. The digestive enzyme is not gotten from the food we eat and therefore must be produced by the body.

Digestion Require 3 types Of Enzymes.

The nutrients in our food come in complex structure bound up in proteins fats and carbohydrates. The cooperative action of these three general types of enzymes is required to release the nutrients in a form that can be absorbed.

  • Proteins require protein-digesting enzymes to break them down into their simple absorbable amino acid components.
  • Fats require lipid digesting enzymes to break them down into their simple absorbable fatty acids components.
  • Carbohydrate requires carbolic enzymes to break them down into their absorbable simple sugar components.

If any of these enzymes are not present in sufficient quantities, digestion can not take place.

Unfortunate as it is, as the body grows old,  enzyme production in most people begins to diminish. In addition, poor feeding habits like eating too fat, overeating or poor food choices may overburden the enzyme supply, and in this case, incomplete digestion may appear. Nutrients will be wasted and intestinal discomfort or medically related problems may arise suddenly.

Food Enzymes.

The human body can not produce food enzymes and depends totally on natural plant food but the unfortunate part here is that most foods are cooked. Therefore, when the temperature of cooking water or heat reaches to a certain degree unbearable for the enzymes, they are destroyed.

The wise thing here would be to eat an adequate amount of raw fruits and vegetable this way one would obtain a sufficient amount of food enzymes. The problem is many people do not eat enough raw foods and thus enzyme deficient. Many others need and depend on supplements to help meet the challenge of daily living. Enzymes should be part of the supplemental program for improved health.


Main Functions Of Enzymes.

The basic function of an enzyme is, they act as the catalyst to speed up chemical reactions. And they do that much faster than ordinary, about a million times faster. Without enzymes, chemical reactions would a long time to happen, that is if it would happen at all.

In human life cycle, enzymes are critical to the existence and normal function of the body as they are involved in almost every aspect of the biochemical reaction that takes place at any given moment in a living being. The continuation of life depends largely on the action of this catalyst – enzymes. The following lines explain how critical enzymes are in the life of humans.

  • Enzymes help transform raw materials into the body cells.
  • Store glycogen in the liver and muscles.
  • Change carbohydrates into fats.
  • Then transform protein into sugar and fats.
  • They work to help to dispose of the waste products of digestion and
  • Enter into just every activity to help maintain life processes.

This is how important enzymes are to the human life cycle, little wonder it is regarded as the missing link of life.


Would Life Be Possible Without Enzymes?

A very vital question here indeed, would life as we know it be possible without enzymes?

Every chemical reaction in a human cell requires the catalytic activities of enzymes to perform quick enough to sustain life. According to Dr. Richard Wolfenden, an Alumni Distinguished Professor Biochemistry and Biophysics and Chemistry at the University of North Carolina at Chapel Hill, in one of his reports stated that, every biochemical reaction in the cell require enzymes to proceed faster, usually in milliseconds and that without enzymes, the same reactions would take about 2.3 billion years to complete,  too scaring, huh? Absolutely scaring.

Now, since every chemical reaction in the body need to proceed fast enough sustain life and it takes about 2.3 billion years for any one reaction to take place without enzymes, how long would life hold on for such chemical reaction to happen without enzymes?

In his conclusion, Dr. Richard Wolfenden noted that there would be no life without these catalysts as both microbes to humans and need it to sustain life.

Many scientific studies over the years have concluded that life would cease to exist without enzymes.
