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.
Yes
It's iron that is found in plants rather than animals. Animal product iron is called heme iron.
In the liver, heme is a component of several vital enzymes, particularly cytochrome P450, involved in the metabolism of chemicals, vitamins, fatty acids, and hormones.
Hemoglobin is a protein with 4 sub-units, each with a heme group that contains one iron atom in it. The iron atom is bound to the heme group by the four nitrogens in the center of the heme, and a histidine that lies beneath the heme group. That leaves a sixth binding site open on the iron to bind an oxygen.
Heme + globin is Hemoglobin.
Heme is decomposed into iron and biliverdin
Heme iron comes from animal sources, while non-heme iron comes from plant sources, so I believe that because mussels are animals, mussels therefore do contain heme iron. Fish also contains heme iron.
When heme levels are low, more delta-aminolevulinic acid (ALA) synthase are produced. Causing larger quantities of heme precursors to be fed into the biosynthesis path producing more heme.
Much of the heme biosynthesis pathway is dedicated to constructing the porphyrin molecule.
The Heme protein database refers to the protein sequence databases.
Heme iron is more efficiently absorbed by the body, but non-heme iron can also be effective if used in conjunction with vitamin C and other dietary sources of heme iron.

4 molecules of oxygen - one to each subunit on the heme
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.
