No (I just noticed this reply to my question). I don't think 'no' really answers it as I know that SOME herbivores definitely do. My question really should have said 'Do ALL herbivores have heme receptors'? A simple no does not give any information. Humans have them for starters and physiologically and anatomically we are herbivores.
More cool receptors than warm receptors in the skin.
nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.
herbivore
Herbivores that live in swamps beavers.
Manatees, sea turtles
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.
The Heme protein database refers to the protein sequence databases.
Much of the heme biosynthesis pathway is dedicated to constructing the porphyrin molecule.
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.
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.
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.
