| hydronium ion | |
| 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. |
| 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. |
| 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) |
| spermidine | A polyamine formed from putrescine. It is found in almost all tissues in association with nucleic acids. It is found as a cation at all pH values, and is thought to help stabilize some membranes and nucleic acid structures. It is a precursor of spermine. |
| 5'-methylthioadenosine | structure |
| putrescine | A toxic diamine formed by putrefaction from the decarboxylation of arginine and ornithine. |
| 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) |
