Although there are enzymes that do not require additional components not be able to perform at its maximum, there are others that do need cofactors to show full activity. Also, there are small organic molecules responsible for transporting chemical groups from one enzyme to another. These are called coenzymes. Examples of these are thiamine, riboflavin, and folic acid and are basically derived from food since the body is unable to produce these molecules.
There are situations in wherein specific enzymes are not adequately produced or taken in by the body causing particular medical conditions. Thus, there are enzyme supplements that are sold in the market to answer to such needs. But aside from supplements, certain enzymes are generally derived from fruits, vegetables, and protein.
Suffice it to say, disorders and irregularities in the human body can be attributed to the enzymes in the body, or the shortage of the necessary enzymes to be exact. You see, each enzyme is assigned with a particular task to perform. It is actually nature’s way of conserving energy.
There are over 2,700 known enzymes in the human body and many are yet to be discovered. Each of these is assigned with a specific task in order to perform efficiently. And collectively, these enzymes give life to an organism.
