👉 Methaemoglobin is a protein found in red blood cells, which are responsible for carrying oxygen from the lungs to the rest of the body. It is produced by the liver and helps transport oxygen to the muscles and other tissues where it can be used as an energy source. However, excessive methaemoglobin can lead to decreased oxygen levels in the blood and contribute to conditions such as sickle cell disease, which affects red blood cells.
