A heme ( American English) or haem ( British English) is a prosthetic group that consists of an iron atom contained in the center of a large heterocyclic organic ring called a porphyrin. Not all porphyrins contain iron, but a substantial fraction of porphyrin-containing metalloproteins have heme as their prosthetic subunit; these are known as hemoproteins. There are several biologically important kinds of heme The most common type is heme B; other important types include heme A and heme C. Isolated hemes are commonly designated by capital letters while hemes bound to proteins are designated by lower case letters. Cytochrome a refers to the heme A in specific combination with membrane protein forming a portion of cytochrome c oxidase. The names of cytochromes typically (but not always) reflect the kinds of hemes they contain cytochrome a contains heme A, cytochrome c contains heme C, etc.

1. Complete Information on Acute intermittent porphyria with Treatment and Prevention
June 19, 2008
Acute sporadic porphyria(AIP) is an uncommon metabolic disorder in the output of heme, the oxygen-binding prosthetic group of hemoglobin. Acute sporadic porphyria is an autosomal predominant disease that results from defects in the enzyme porphobilinogen-deaminase. This enzyme speeds the transition of porphobilinogen to hydroxymethylbilane. In AIP, the porphyrin precursors, porphobilinogen and amino-levulinic acid, amass. Additional factors must too be existing such as hormones, drugs, and dietary changes that spark the show of symptoms. Symptoms of AIP may include abdominal pain, impairment, ... (read more)

2. Erythropoietic Protoporphyria - Prevention Tips and Treatment Methods
January 31, 2008
EP is primarily a disorder of bone marrow heme synthesis. It occurs most often in whites but can also occur in people of any origin. Erythropoietic protoporphyria occurs equally in men and women. EP occurs in both males and females with approximately equal frequencies. More than 85 different mutations of the ferrochelatase gene have been identified to date. EP typically occurs in infants or young children. EPP is inherited as an autosomal dominant trait with poor penetrance. Swelling, burning, itching, and redness of the skin may appear during or after exposure to sunlight, including sunlight ... (read more)

3. Porphyria Cutanea Tarda Facts and Treatment
December 15, 2007
The porphyrias are a group of diseases in which there is a defect somewhere in the complex chain of chemical steps that are required for the synthesis of the molecule known as haem.
Haem is one of a group of compounds called porphyrins and is an iron-containing molecule that combines with the protein globin to form haemoglobin..The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of the body's organs. It is a component of hemoglobin, the molecule that carries oxygen in the blood. PCT is essentially an acquir... (read more)

4. Porphyria Cutanea Tarda Treatment Tips
November 30, 2007
Porphyria cutanea tarda (PCT) is the most common type of porphyria. PCT is frequently associated with hepatitis C virus (HCV) infection. Porphyria cutanea tarda is the most common porphyria and causes blistering of skin exposed to sunlight. Several common factors (precipitating factors) are associated with porphyria cutanea tarda; these include excess iron in body tissues, moderate or heavy alcohol use, infection with hepatitis C virus, and possibly smoking.The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of ... (read more)

5. Heartburn, Drugs, and Low Iron
June 06, 2007
Most people and doctors think it is ok to use drugs for heartburn, acid reflux, or gastroesophageal disease. Drugs for these diseases should be used sparingly and should be watched closely by the doctor. Drugs should be used for a short time to give the patient time to heal any tissue damage caused by stomach acid going back into the esophagus. Even so, natural remedies can also heal tissue damage in the esophagus and cure heartburn.
Drugs are designed to neutralized or reduce acid strength or to stop the stomach lining from creating more acid. The stomach automatically produces more ... (read more)

6. Anemia - Herbal treatment, Ayurvedic Remedies and Home Remedies
February 17, 2007
What is Anemia?
Anemia is a condition in which the blood is deficient in the body. This deficiency of blood is caused due to the deficiency of iron, which is an essential component of the protein complex, hemoglobin, present in the blood.
In anemic persons, the count of hemoglobin in the blood goes down. Hemoglobin is composed of heme, which is an iron complex, and a protein named globin. If iron is lacking in the diet, then heme will not be formed and so also hemoglobin. The main function of hemoglobin is to carry oxygen to different parts of the body. Hence in absence of hemoglobin... (read more)

7. Iron, Benefits of Iron, Iron Deficiency and Iron Rich Foods
February 16, 2007
Iron is an essential mineral for life. It is found in the red blood cells of the body and is also needed to produce red blood cells. Most of the iron in the body is attached to the haemoglobin molecules in red blood cells, thereby transporting oxygen to all the tissues of the body. Haemoglobin is the essential protein found in red blood cells and represents about two thirds of the body's iron. When red blood cells die, the iron in them is recycled in the bone marrow to be used again in new red blood cells. Myoglobin is the heme-containing protein that is involved in the transport a...

8. Iron-rich foods
September 18, 2006
There are two types of iron – heme (found in animal products) and non-heme (found in plant sources). Heme iron is far easier to absorb from food and is found abundantly in red meat. Non-heme iron on the other hand is much harder to absorb and in addition is found in much smaller quantities in plant-based products. This is why vegetarians have difficulty maintain adequate iron stores and why they are prone to anemia. Iron-deficient anemia is a major cause of chronic tiredness.
Foods that contain heme-iron
Red meat (beef, lamb, pork, offal) is rich in iron that is easily absorbed. The ... (read more)
