| Compound | Description |
|---|
| phosphoric acid | concise etchant is 37% H3PO4 |
| 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. |
| 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) |
| NADH | |
| ergosterol | A steroid occurring in FUNGI. Irradiation with ULTRAVIOLET RAYS results in formation of ERGOCALCIFEROL (vitamin D2). |
| 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. |
| squalene | A natural 30-carbon triterpene. |
| hydrogen carbonate | |
| 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. |
| presqualene pyrophosphate | |
| isopentenyl pyrophosphate | substrate for isopentenyl pyrophosphate isomerase; RN given refers to unlabeled cpd; a nonpeptide mycobacterial antigen that stimulates gamma delta T cells |
| 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) |

| geranyl pyrophosphate | RN given refers to (E)-isomer |
| Mevalonate | |
| 2,3-oxidosqualene | an oxidized derivative of SQUALENE that can fold in several ways: chair-boat-chair-boat to LANOSTEROL; chair-chair-chair-boat to dammarane; or all chair to hopane and on to cycloartenol; RN given refers to (all-Z)-isomer |
| glutamate | |
| leucine | An essential branched-chain amino acid important for hemoglobin formation. |
| acetoacetate | |
| lanosterol | A triterpene that derives from the chair-boat-chair-boat folding of 2,3-oxidosqualene. It is metabolized to CHOLESTEROL and CUCURBITACINS. |
| Coenzyme A | |
| s-adenosylhomocysteine | 5'-S-(3-Amino-3-carboxypropyl)-5'-thioadenosine. Formed from S-adenosylmethionine after transmethylation reactions. |
| phosphomevalonate | |
| Acetyl Coenzyme A | Acetyl CoA participates in the biosynthesis of fatty acids and sterols, in the oxidation of fatty acids and in the metabolism of many amino acids. It also acts as a biological acetylating agent. |
