| Compound | Description |
|---|---|
| Glutathione | A tripeptide with many roles in cells. It conjugates to drugs to make them more soluble for excretion, is a cofactor for some enzymes, is involved in protein disulfide bond rearrangement and reduces peroxides. |
| sapropterin | RN given refers to parent cpd; co-factor required for catalytic activity of nitric oxide synthases |
| ammonium hydroxide | The hydroxy salt of ammonium ion. It is formed when AMMONIA reacts with water molecules in solution. |
| 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. |
| levodopa | The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system. |
| tyrosine | A non-essential amino acid. In animals it is synthesized from PHENYLALANINE. It is also the precursor of EPINEPHRINE; THYROID HORMONES; and melanin. |
| flavin-adenine dinucleotide | A condensation product of riboflavin and adenosine diphosphate. The coenzyme of various aerobic dehydrogenases, e.g., D-amino acid oxidase and L-amino acid oxidase. (Lehninger, Principles of Biochemistry, 1982, p972) |
| Dopamine | One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action. |
| 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. |
| 4a-hydroxytetrahydrobiopterin | structure given in first source |
| 5,6-dihydroxy-2-indolylcarboxylic acid | |
| leukodopachrome | proposed metabolite in pathway from tyrosine to dopachrome; RN given refers to (S)-isomer; structure given in first source |
| dopamine quinone | product of the autoxidation of dopamine |
| 3-methoxytyramine | RN given refers to parent cpd |
| homovanillic acid | A 3-O-methyl ETHER of (3,4-dihydroxyphenyl)acetic acid. |
| dopaquinone | proposed metabolite in pathway from tyrosine to dopachrome; RN given refers to cpd without isomeric designation; structure given in first source |
| 3,4-dihydroxyphenylacetic acid | A deaminated metabolite of LEVODOPA. |
| dinitrochlorobenzene | A skin irritant that may cause dermatitis of both primary and allergic types. Contact sensitization with DNCB has been used as a measure of cellular immunity. DNCB is also used as a reagent for the detection and determination of pyridine compounds. |
| 5,6-dihydroxyindole | |
| 3,4-dihydroxyphenylacetaldehyde | |
| n-methylserotonin | RN given refers to parent cpd |
| (4-hydroxy-3-methoxyphenyl)acetaldehyde | structure given in first source |
| aminochrome 1 | |
| s-adenosylhomocysteine | 5'-S-(3-Amino-3-carboxypropyl)-5'-thioadenosine. Formed from S-adenosylmethionine after transmethylation reactions. |
| 3,4-dihydroxyphenylethanol | serotonin metabolite; structure |
