They act as catalysts in a myriad of biochemical reactions. Intriguingly, every single function in our body, from blinking to digesting food, involves the essential role of enzymes. Composition of Enzymes What are enzymes made of? Primarily, they are proteins made up of amino acids. These amino acids link together in a sequence, giving the enzyme its unique structure. This structure determines the enzyme's specific function. Undeniably, enzymes are complex. They are built from chains of amino acids, folded into a three-dimensional shape. This shape is critical. It includes an area known as the active site, where the magic happens. Types Of Enzymes • Digestive Enzymes: These enzymes break down food into smaller molecules that your body can absorb. Amylase and protease are examples of digestive enzymes. • Metabolic Enzymes: These enzymes speed up chemical reactions in the body's cells. They play a vital role in the growth, reproduction, and survival of cells. • Food Enzymes: These enzymes are found naturally in raw foods. They aid in the digestion and absorption of food. • Each type of enzyme has a specific role. However, all work together to maintain your body's overall health. How Enzymes Works • let's ponder how enzymes work. Enzymes operate on a lockand-key principle. The molecule that an enzyme acts upon, termed the "substrate", fits into the enzyme's active site. When the substrate enters the enzyme's active site, a reaction takes place. This reaction changes the substrate into a new molecule, known as the product. The enzyme then releases the product and is ready to start the process again with a new substrate. Despite their complexity, enzymes are remarkably efficient. They can catalyze thousands of reactions per second, making them indispensable to life. More About Enzymes • Enzymes in Action To further illustrate, let's consider an example. The enzyme amylase, found in saliva, breaks down starch into sugar. Here's how it works: • The starch molecule fits into the active site of the amylase enzyme. • The enzyme breaks the starch down into sugar molecules.
