Cells are made up of many substances, especially carbohydrates, lipids, nucleic acids and protein. Their main functions are protein synthesis and transmission and interpretation of hereditary information. There are thousands of different kinds of protein, each performing a specific purpose, and almost every function within a cell involves protein. Proteins are essential constituents of the body, the building blocks of muscles, tissues, and organs, and proteins regulate functions of enzymes and hormones. Proteins are synthesized in the body from their constituent amino acids which are obtained from digestion of protein in the diet.
Enzymes speed up the reaction by increasing the frequency of colliding molecules.
In other words, enzymes speed up a biological reaction by binding with the substance involved in the reaction. Coenzymes are often vitamin derivatives. This is all very complex and a good deal more academic than intended but it is important to explain the role of enzymes. Researchers are learning that certain enzymes are vital in maintaining health, and preventing diseases. Enzymes are effective in fighting inflammatory diseases, improving circulation, decreasing the rate of inflammation, aiding in tissue repair, complementing autoimmune therapy, and of course, the digestion of food.
