Hemosiderin, in contrast to ferritin, is an amorphous iron-containing substance with no fixed composition. It consists of conglomerates of clumped ferritin particles, denatured proteins, and lipids. The iron within hemosiderin is insoluble, but is in equilibrium with the soluble ferritin pool.
What foods to avoid if you have high ferritin levels?
- The reduction in red meat consumption
- The avoidance of animal fat and sugar
- Limitation of vitamin C from all sources
- The moderate use of alcohol
- Increased intake of whole grains, rice, and beans
- The consumption of tea and coffee

What is the difference between ferritin and transferrin?
The four most frequent iron-related tests are::
- serum iron- measures iron levels in serum; represents iron that is almost completely bound to transferrin;
- transferrin- measures levels of the iron carrier;
- total iron binding capacity (TIBC)- measures the transferrin capacity to bind iron;
- serum ferritin- measures the body's ability to store iron.
What is dangerous iron levels?

Is ferritin and hemosiderin same?
Ferritin is a protein with a capacity of about 4500 iron (III) ions per protein molecule. This is the major form of iron storage. If the capacity for storage of iron in ferritin is exceeded, a complex of iron with phosphate and hydroxide forms. This is called hemosiderin; it is physiologically available.
Does ferritin contain more iron than hemosiderin?
Ferritin and hemosiderin have high affinity and sensitivity to iron however, ferritin stores slightly more iron than hemosiderin in low iron conditions such as iron deficiency anemia, whereas in iron overload hemosiderin stores more iron than ferritin [26] . ...
What is the role of hemosiderin?
Hemosiderin is one of the proteins (along with ferritin) that stores iron in your body's tissue. Excessive accumulation of hemosiderin in tissues causes hemosiderosis. This condition is different from hemochromatosis, which is an inherited condition that causes you to absorb too much iron from food.
What is the meaning of hemosiderin?
Definition of hemosiderin : a yellowish-brown, iron-containing, granular pigment that is found within cells (such as macrophages), is composed chiefly of aggregates of ferritin, and is typically associated with bleeding and the breakdown of red blood cells (as in hemolytic anemia)
What is ferritin hemosiderin?
Hemosiderin and ferritin are iron-containing proteins with magnetic susceptibility. Hemosiderin is water-insoluble and thermally denatured, but ferritin is water-soluble and heat-resistant up to 75°C. These characteristic differences were used for the fractionation of ferritin and hemosiderin.
Is hemosiderin normal?
In normal animals, hemosiderin deposits are small and commonly inapparent without special stains. Excessive accumulation of hemosiderin is usually detected within cells of the mononuclear phagocyte system (MPS) or occasionally within epithelial cells of the liver and kidney.
Can too much iron cause hemosiderin?
Hemosiderosis is a term used for excessive accumulation of iron deposits called hemosiderin in the tissues. (See also Overview of Iron Overload. People lose small amounts of iron every day, and even a... read more .) Organs may be damaged by the iron deposits.
Where is hemosiderin found in the body?
Hemosiderin (iron-positive, golden brown granules) is normally found in macrophages primarily in the red pulp but also within the marginal zone to a lesser degree.
What does hemosiderin look like?
Hemosiderin — a protein compound that stores iron in your tissues — can accumulate under your skin. As a result, you may notice yellow, brown, or black staining or a bruiselike appearance. Stains most often appear on the lower leg, sometimes covering the space between your knee and ankle.
What ferritin means?
Ferritin is a blood protein that contains iron. A ferritin test helps your doctor understand how much iron your body stores. If a ferritin test reveals that your blood ferritin level is lower than normal, it indicates your body's iron stores are low and you have iron deficiency.
What is the difference between hemochromatosis and hemosiderosis?
Hemochromatosis and hemosiderosis are two conditions associated with having too much iron in the body. In some cases, this can affect the liver. Hemochromatosis is a condition where a person has too much iron in their body. In hemosiderosis, iron deposits in organs such as the liver, pancreas, and skin.
How is hemosiderin involved in iron transport?
Transferrin is the major iron transport protein (transports iron through blood). Fe3+ is the form of iron that binds to transferrin, so the Fe2+ transported through ferroportin must be oxidized to Fe3+....12.72 Iron Transport & Storage.MenWomenTransport ironTransferrin0.040.046 more rows
What is high iron called?
Haemochromatosis is an inherited condition where iron levels in the body slowly build up over many years. This build-up of iron, known as iron overload, can cause unpleasant symptoms. If it is not treated, this can damage parts of the body such as the liver, joints, pancreas and heart.
Is ferritin and transferrin the same thing?
Transferrin is the main iron transporting protein in the circulation. Ferritin concentrations reflect the body's iron stores.
What is the difference between ferritin and transferrin?
Ferritin refers to a protein produced in mammalian metabolism which serves to store iron in the tissues while transferrin refers to a plasma protein that transports iron through the blood to the liver, spleen and bone marrow. This explains the basic difference between ferritin and transferrin.
How does ferritin work?
Ferritin is made up of 24- peptide subunits, which surround a core of iron atoms. Small channels are responsible for the transportation of iron in and out of the core. These channels are made up of the intersection of three peptides and, they are called a three-fold channel. They are lined with polar amino acids such as Glutamate or Aspartate. The polarity of amino acids allows the iron atoms to make interactions with water. Another type of intersections called four-fold channels, which is made up of an intersection of four peptides, occurs in the ferritin and they are lined with Leucine, a non-polar amino acid. These channels allow the transport of electrons required by the reduction of iron in the core. Actually, the core comprises iron in the form of Fe (III), which takes up an electron to reduce into Fe (II). When the iron atoms become Fe (II), they can diffuse out from the core. In general, a core inside one ferritin molecule can store up to 4,300 iron atoms.
What are the two types of iron binding proteins?
Ferritin and transferrin are two types of iron-binding proteins in the body. Both of them play a vital role in maintaining the iron levels in the body.
What is transferrin protein?
What is Transferrin. Transferrin is the iron-binding protein responsible for the transport of iron in the blood and body fluids. It is a globular protein found in plasma. The size of transferrin is 80 kDa and it has two specific sites for the binding of iron in the form of Fe (II). These sites consist of tyrosine phenoxy groups, ...
How many iron atoms are in a ferritin core?
When the iron atoms become Fe (II), they can diffuse out from the core. In general, a core inside one ferritin molecule can store up to 4,300 iron atoms.
What is the reference range for ferritin?
The reference range of ferritin is 30–300 ng/mL for males and 18–160 ng/mL for females while the reference range of transferrin is 204–360 mg/dL in the blood.
Where is ferritin found in the body?
It is a universal biomolecule found in animals, plants, bacteria, and archaea. In mammals, it mainly occurs in the cytoplasm of the cells, in bone marrow, liver, and spleen. Hence, the amounts of transferrin in the cytoplasm depends on the function of the cell.
What is the Difference Between Serum Iron and Ferritin?
Serum iron is the amount of circulating iron bound to transferrin and serum ferritin, while ferritin is an intracellular protein that stores iron in the cell and releases it in a controlled manner. So, this is the key difference between serum iron and ferritin. Furthermore, serum iron is measured through serum iron test, while ferritin is measured through serum ferritin or ferritin test.
Where is ferritin produced?
Ferritin is produced in most tissues as a cytosolic protein. A small amount secretes into the serum where it functions as an iron carrier. Furthermore, serum ferritin is a diagnostic test for iron deficiency anaemia. The normal ferritin reference ranges in blood for men are 18-270 ng/mL, and for women are 30-160 ng/mL.
What is Serum Iron?
Serum iron is the amount of circulating iron bound to transferrin and serum ferritin. Serum iron test measures this amount of circulating iron. Normally, 90 % of serum iron is bound to transferrin transport protein. The rest of the 10 % of serum iron is stored in ferritin. Doctors order this test when they suspect an iron deficiency. Iron deficiencies can cause anaemia and other health problems. Usually, 65 % of the iron in the body is in the haemoglobin in red blood cells. Approximately 4 % is in myoglobin molecules. Around 30 % of iron is stored in ferritin or hemosiderin in the spleen, bone marrow and liver. A small amount of iron can be found in other molecules in the cells. None of this iron is directly accessible through testing the serum. Anyhow, some iron is circulating in the serum. Transferrin is a molecule produced by the liver that binds to one or two irons. Circulating iron is mainly bound to transferrin protein. The test for serum iron measures the iron ions that are bound to transferrin and stored in serum ferritin. Moreover, the normal serum iron reference ranges for men are 65 to 176 μg/dL and for women are 50 to 170 μg/dL.
Why is a serum iron test important?
Serum iron test is an important tool for the diagnosis process of conditions such as anaemia, iron deficiency anaemia, anaemia of chronic disease and haemochromatosis.
Is iron a nutrient?
Iron is an essential nutrient. It has many functions, such as the production of healthy red blood cells. It is a very important part of haemoglobin. The body cannot produce iron on its own, so it has to absorb iron from food and supplements. Normally, iron is transported in the body through a protein known as transferrin. In healthy people, most of the iron in the body is incorporated into haemoglobin in red blood cells. The remaining iron is stored in ferritin. Therefore, serum iron and ferritin help to evaluate iron in the body.
What is the difference between hemochromatosis and hemosiderosis?
Hemochromatosis is the systemic deposition of iron that causes tissue damages in the human body , while hemosiderosis is the focal deposition of iron that does not cause any tissue damages in the human body . So, this is the key difference between hemochromatosis and hemosiderosis. Furthermore, the accumulation of hemosiderin is not seen in hemochromatosis. But, accumulation of hemosiderin is seen in hemosiderosis.
What is Hemosiderosis?
Hemosiderosis is the focal deposition of iron that does not cause any tissue damages in the human body. It is a form of iron overload disorder result ing in the accumulation of hemosiderin. In this condition, the iron liberated from extravasated red blood cells is deposited within the organ and significant hemosiderin deposits may eventually develop in that organ. Chronic inflammatory syndromes such as non-alcoholic fatty liver disease and metabolic syndrome can cause hemosiderosis.
What is Hemochromatosis?
Hemochromatosis is the systemic deposition of iron that cause tissue damages in the human body. We also call this an iron overload. This condition is often genetic. It can cause serious damages to the heart, liver, and pancreas. Too much iron can be toxic. In the heart, it can cause arrhythmia and heart failure. Too much iron in the liver can lead to cirrhosis, enlarged liver, liver cancer, and liver failure. In addition, it can also cause arthritis, diabetes, problems in the spleen, pituitary gland, adrenal gland, gall bladder, thyroid, and reproductive system. An iron overload can cause the skin to look more gray or bronze. Hemochromatosis is fairly common, and it affects more than a million Americans.
What is the name of the disease that causes iron deposition?
Hemochromatosis and hemosiderosis are two iron deposition diseases.
What are the three types of hemosiderosis?
Hemosiderosis can be divided into three types: transfusion hemosiderosis, idiopathic pulmonary hemosiderosis, and transfusional diabetes hemosiderosis. Symptoms of this condition may include coughing, difficulty in breathing, fatigue, shortness of breath, pain in the body, wheezing, and slow growth in children. There are several tests to diagnose this condition: serum ferritin, liver biopsy and MRI. Furthermore, the treatments may include iron chelation therapy, stopping blood transfusions, corticosteroids for bleeding in the lungs, oxygen therapy for lung conditions, anticoagulants for pulmonary hypertension and lung transplants.
What are the two types of hemochromatosis?
There are two types of hemochromatosis: they are hereditary (primary) and secondary. Hereditary hemochromatosis is due to a mutation of several genes such as HFE, HJV, HAMP, and SLC40A1. On the other hand, secondary hemochromatosis is due to medical treatments or other medical conditions like anemia, blood transfusion, iron pills, kidney dialysis, hepatitis C infection, and fatty liver disease. Symptoms of hemochromatosis may include fatigue, heart flutters, iron fist, joint pain, stomach pain, and unexplained weight loss. This condition is usually diagnosed through blood tests, genetic tests, liver biopsies, and MRI. Furthermore, the treatments may include changes to diet, iron chelation therapy, and therapeutic phlebotomy.
How much iron does a woman lose in a day?
Adults usually lose 1mg iron per day from epidermal and gastrointestinal cells. Menstruating women lose an additional 0.5 to 1 mg iron per day from menses. This iron loss is balanced by absorption of iron around 10 to 20 mg in a typical diet. Iron absorption is regulated based on the iron stores in the body. Since there is no physiologic mechanism to remove iron from the body, the excess iron absorbed is deposited in tissues.
