Iron is an essential part of the proteins that transport oxygen in the body. Hemoglobin, the oxygencarrying protein in red blood cells, accounts for about two-thirds of the body’s iron supply. Smaller amounts are found in myoglobin, the protein that supplies oxygen to muscles, and in enzymes needed for various biochemical reactions.

Hemophilia is a group of hereditary genetic disorders that impair the body's ability to control blood clotting or coagulation, which is used to stop bleeding when a blood vessel is broken. It has been associated with royal families due to inbreeding, and is sometimes called the 'Royal Disease.’

Acute kidney failure (AKF) occurs when there is a sudden reduction in kidney function that results in nitrogenous wastes accumulating in the blood (azotemia). The accumulation of nitrogenous wastes is known as uremia. If untreated, uremia can cause coma and eventually death.

Haemoglobin is an iron-containing protein in red blood cells. Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the rest of the body (i.e. the tissues) where it releases the oxygen to burn nutrients to provide energy to power the functions of the organism, and collects the resultant carbon dioxide to bring it back to the respiratory organs to be dispensed from the organism.

Glycogen, the major reservoir of carbohydrate in the body, is comprised of long chain polymers of glucose molecules. The body stores approximately 450-550 grams of glycogen within the muscle and liver for use during exercise. At higher exercise intensities, glycogen becomes the main fuel utilized. Depletion of liver glycogen has the consequence of diminishing liver glucose output, and blood glucose concentrations accordingly.
