| Compound | Description |
|---|
| iron | A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN. |
| Carbon Dioxide | A colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals. |
| s-adenosylmethionine | Physiologic methyl radical donor involved in enzymatic transmethylation reactions and present in all living organisms. It possesses anti-inflammatory activity and has been used in treatment of chronic liver disease. (From Merck, 11th ed) |
| methionine | A sulfur-containing essential L-amino acid that is important in many body functions. |
| vitamin k 2 | A group of substances similar to VITAMIN K 1 which contains a ring of 2-methyl-1,4-naphthoquinione and an isoprenoid side chain of varying number of isoprene units. In vitamin K 2, each isoprene unit contains a double bond. They are produced by bacteria including the normal intestinal flora. |
| uroporphyrinogen iii | |
| protoporphyrinogen | |
| coproporphyrinogen iii | |
| 5'-deoxyadenosine | main heading DEOXYADENOSINE refers to the 3' cpd |
| protoporphyrin ix | RN given refers to parent cpd; structure in Merck Index, 9th ed, #7685 |
| Hydrogen | The first chemical element in the periodic table with atomic symbol H, and atomic number 1. Protium (atomic weight 1) is by far the most common hydrogen isotope. Hydrogen also exists as the stable isotope DEUTERIUM (atomic weight 2) and the radioactive isotope TRITIUM (atomic weight 3). Hydrogen forms into a diatomic molecule at room temperature and appears as a highly flammable colorless and odorless gas. |
| heme | The color-furnishing portion of hemoglobin. It is found free in tissues and as the prosthetic group in many hemeproteins. |
