Jewish World Review How Stuff Works: How poisons work By Marshall Brain http://www.JewishWorldReview.com | (MCT) Just about every day we hear about different poisons. You probably know that carbon monoxide can kill you, and so can cyanide. Lead is a poison that is in the news all the time. Occasionally you will see a story about someone eating a poison mushroom or eating a poisonous Castor bean. The question is, what makes a poison a poison? Why do people die if they eat a certain type of plant or breathe a certain gas? Although every poison works differently, they all do the same thing. Poisons get into your body and gum up something essential in your body's cells. Without that essential something, your cells die, and so do you. Take, for example, the gas known as carbon monoxide. This poison is produced when things burn. Car exhaust contains carbon monoxide. If you have a furnace that burns oil or natural gas, it can produce carbon monoxide (and has an exhaust stack that sends the carbon monoxide outside). If you have a fireplace and the chimney doesn't work properly, burning wood will send carbon monoxide into your home. When you inhale carbon monoxide, it enters your lungs. Inside your lungs, the goal is for red blood cells to release carbon dioxide and to pick up oxygen. But if there is carbon monoxide in the air, it locks into red blood cells at the place where the oxygen normally attaches. And once in a red blood cell, it is very hard to get the carbon monoxide out. Eventually, if you breathe enough of it, all of your red blood cells get polluted with carbon monoxide and cannot carry any oxygen. At that point, all of the cells in your body suffocate from lack of oxygen, and you die. Lead is another common poison, and is especially harmful in growing children. The problem with lead is that, to your cells, lead looks a lot like other metal atoms like iron and calcium. Lead replaces calcium in bones. It also replaces calcium that is used inside the brain to keep your neurons firing properly. In children this causes the brain to develop and function incorrectly, leading to lower intelligence and other problems. Arsenic is a poison made famous by the play "Arsenic and Old Lace." Less than a gram of it will kill an adult. Like lead, it poisons by mimicry. In the case of arsenic, it mimics phosphate. Phosphate, it turns out, is essential to the chemical reaction that provides human cells with energy. So arsenic essentially cuts off the energy supply to all the cells in your body, and you die. Castor beans contain a poison known as ricin. Ricin is a protein that enters cells and attaches to ribosomes. Once attached, the ribosomes stop working. Ribosomes are essential to your cells because they manufacture all the proteins and enzymes used inside the cell. Without the ability to create new enzymes, your cells eventually die. And so do you. Death cap mushrooms contain a chemical that gums up another part of the protein assembly line. Acetaminophen, the common pain killer best known as Tylenol, is a liver poison if you take too much. In the normal case, the liver processes Acetaminophen and eliminates it from the blood stream. This is why you have to take Acetaminophen every few hours. But if you take too much Acetaminophen (say 10 grams of it), the normal process gets overwhelmed. The liver then uses a different process, which creates a chemical that kills liver cells. Without a liver, you die. And then there is cyanide, which acts very quickly. A cyanide molecule, like carbon monoxide, takes up a place where oxygen binds to iron. In this case, the iron is part of the energy-production machinery in your cells. The cells can't produce energy and die in just a few minutes. Because cyanide is so quick, it has been a common poison used in gas chambers and suicide pills. Your body is a very complex and fascinating chemical machine containing millions of different chemical reactions. All of these poisons disrupt a chemical reaction in some way. To be a deadly poison, all the chemical has to do is disrupt a chain that is essential to life.
