Part Description

LP16466-2   Hemosiderin
Hemosiderin or haemosiderin is an abnormal microscopic pigment found in the human body. Hemosiderin is composed of iron oxide and can accumulate in different organs in various diseases. Iron is required by many of the chemical reactions in the body but is toxic when not properly contained. Thus, many methods of iron storage have developed. Humans typically store iron within a protein called ferritin. The form of iron in ferritin is iron(III) oxyhydroxide. By complexing with ferritin, the iron is made water soluble. Several diseases result in deposition of iron(III) oxyhydroxide in tissues in an insoluble form. These deposits of iron are called hemosiderin. Although these deposits often cause no symptoms, they can lead to organ damage. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
