=== How does Iron Affect Ferroptosis? ===
Iron is important in our body. Usually, it travels in our blood and enters cells. But if there's too much iron in a cell, it can cause a reaction that makes harmful molecules called ROS. These molecules can damage the cell and start ferroptosis. Some proteins and genes in our body can control this process. For example, a protein called "heat shock protein β1" can help stop ferroptosis by controlling the amount of iron in cells.
