Understanding the Basics of Enzyme Biochemistry
Enzymes are amazing biological helpers that are key in our bodies’ metabolic pathways. They speed up chemical reactions, helping us break down nutrients and make new molecules. Knowing about enzyme markers in medicine starts with understanding enzyme biochemistry basics.
Enzymes are made of amino acids that fold into shapes. These shapes let them bind to specific molecules, called substrates. This binding happens at the enzyme’s active site, making reactions faster without using up the enzyme.
How fast enzymes work depends on things like how much substrate there is, the temperature, and the pH. By studying this with enzyme assays, scientists learn a lot about how enzymes work. These assays measure how fast products are made or substrates are used up.
Enzymes are linked to the metabolic pathways that keep our cells working right. These pathways change one molecule into another, with enzymes helping at each step. They help break down food into energy and make important compounds like hormones.
When enzymes work well, our body’s pathways run smoothly. But if they don’t, it can mean there’s a health problem. For example, high levels of liver enzymes can mean liver damage. High levels of pancreatic enzymes can mean pancreatitis.
Healthcare workers use enzyme biochemistry to understand test results and diagnose diseases. As we learn more about enzymes, we’ll be able to use them in new ways. This could lead to better early detection and treatment in the future.
