| hydronium ion | |
| pyridoxal | The 4-carboxyaldehyde form of VITAMIN B 6 which is converted to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. |
| pyridoxal phosphate | This is the active form of VITAMIN B 6 serving as a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into pyridoxamine phosphate (PYRIDOXAMINE). |
| pyridoxine | The 4-methanol form of VITAMIN B 6 which is converted to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990). |
| pyridoxine 5-phosphate | RN given refers to parent cpd |
| pyruvic acid | An intermediate compound in the metabolism of carbohydrates, proteins, and fats. In thiamine deficiency, its oxidation is retarded and it accumulates in the tissues, especially in nervous structures. (From Stedman, 26th ed) |
| Orthophosphate | |
| Carbon Dioxide | A colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals. |
| glutamic acid | A non-essential amino acid naturally occurring in the L-form. Glutamic acid is the most common excitatory neurotransmitter in the CENTRAL NERVOUS SYSTEM. |
| NADH | |
| Adenosine Triphosphate | An adenine nucleotide containing three phosphate groups esterified to the sugar moiety. In addition to its crucial roles in metabolism adenosine triphosphate is a neurotransmitter. |
| adenosine diphosphate | Adenosine 5'-(trihydrogen diphosphate). An adenine nucleotide containing two phosphate groups esterified to the sugar moiety at the 5'-position. |
| Hydrogen Peroxide | A strong oxidizing agent used in aqueous solution as a ripening agent, bleach, and topical anti-infective. It is relatively unstable and solutions deteriorate over time unless stabilized by the addition of acetanilide or similar organic materials. |
| 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. |
| pyridoxamine | The 4-aminomethyl form of VITAMIN B 6. During transamination of amino acids, PYRIDOXAL PHOSPHATE is transiently converted into pyridoxamine phosphate. |
| pyridoxamine phosphate | RN given refers to parent cpd; structure |
| erythrose 4-phosphate | RN given refers to (R-(R*,R*))-isomer |
| 2-amino-3-phosphonopropionic acid | metabotropic glutamate receptor antagonist; do not confuse AP-3 used as an abbreviation for this with enhancer-binding protein AP-3 (a trans-activator) or clathrin assembly protein AP-3 |
| alpha-ketoglutaric acid | |
| 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) |
| Glyceraldehyde 3-Phosphate | An aldotriose which is an important intermediate in glycolysis and in tryptophan biosynthesis. |
| 4-phosphothreonine | structure in first source |
| 1-deoxy-d-xylulose 5-phosphate | |
