Primary biosynthesis sites are the liver and the bone marrow.
Non-heme iron refers to the form of iron found in plant-based foods and supplements, whereas heme iron is the type found in animal-based foods like meat, fish, and poultry. Non-heme iron is not as easily absorbed by the body as heme iron, so consuming it alongside vitamin C can help enhance its absorption.
Heme iron
Heme iron is much more absorbable than non-heme iron. Since the iron inanimal-based foods is about 40% heme iron and 60% non-heme iron, animal-basedfoods are good sources of absorbable iron. In contrast, all of the iron found in plantbasedfoods is non-heme iron. Meat, fish, and poultry also contain a special meatfactor that enhances the absorption of non-heme iron. Vitamin C (or ascorbic acid)also enhances the absorption of non-heme iron.
Heme Iron
Heme is a ferrous ion prosthetic group (Fe2+) present in metalloproteins or specifically Hemoproteins such as Hemoglobin, porphyrin. heme is also found in proteins such as myoglobin, catalase, cytochromes. In these proteins Heme either participates in the catalysis or act as a stabilizer of active site amino acid.
The organometallic iron compound found in hemoglobin is called heme. Heme is a complex of iron and a porphyrin molecule, specifically protoporphyrin IX, which is responsible for binding oxygen in red blood cells.
The two main forms of iron found in food are heme iron, which comes from animal sources like meat and fish, and non-heme iron, which comes from plant sources like spinach and lentils. Heme iron is more easily absorbed by the body compared to non-heme iron.
A heme protein found in straited skeletal and cardiac muscles
Heme is a molecule that contains iron and is found in hemoglobin, the protein in red blood cells responsible for carrying oxygen throughout the body. It plays a crucial role in oxygen transportation and storage in the body. Heme can also be found in myoglobin, a protein that stores oxygen in muscle cells.
Heme + globin is Hemoglobin.
Heme is decomposed into iron and biliverdin
Hemoglobin is a protein found in red blood cells that functions to transport oxygen throughout the body. It is composed of a heme group, which contains iron and binds with oxygen, and globin chains, which provide the structure for the heme groups. The interaction between heme and globin allows hemoglobin to efficiently transport oxygen from the lungs to the body's tissues.
