Compounds (10)
| Compound | Description |
|---|
| hydronium ion | |
| Carbon Dioxide | A colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals. |
| NADH | |
| vitamin k semiquinone radical | found in active preparations of vitamin K-dependent carboxylase |
| Water | A clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances. The chemical formula is hydrogen oxide (H2O). (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed) |
| Oxygen | An element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration. |
| dithiothreitol | A reagent commonly used in biochemical studies as a protective agent to prevent the oxidation of SH (thiol) groups and for reducing disulphides to dithiols. |
| vitamin k1 hydroquinone | metabolite of vitamin K1 & vitamin K1 2,3-epoxide |
| NAD | A coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH). (Dorland, 27th ed) |
| vitamin K1 oxide | RN given refers to parent cpd; see also record for 2,3-epoxymenaquinone |
