| Compound | Description |
|---|
| phosphoric acid | concise etchant is 37% H3PO4 |
| hydronium ion | |
| guanosine monophosphate | A guanine nucleotide containing one phosphate group esterified to the sugar moiety and found widely in nature. |
| adenine | A purine base and a fundamental unit of ADENINE NUCLEOTIDES. |
| ammonium hydroxide | The hydroxy salt of ammonium ion. It is formed when AMMONIA reacts with water molecules in solution. |
| 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. |
| adenosine monophosphate | Adenine nucleotide containing one phosphate group esterified to the sugar moiety in the 2'-, 3'-, or 5'-position. |
| adenosine | A nucleoside that is composed of ADENINE and D-RIBOSE. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter. |
| phosphoribosyl pyrophosphate | The key substance in the biosynthesis of histidine, tryptophan, and purine and pyrimidine nucleotides. |
| 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) |
| guanine | |
| guanosine | A purine nucleoside that has guanine linked by its N9 nitrogen to the C1 carbon of ribose. It is a component of ribonucleic acid and its nucleotides play important roles in metabolism. (From Dorland, 28th ed) |
| inosinic acid | |
| hypoxanthine | A purine and a reaction intermediate in the metabolism of adenosine and in the formation of nucleic acids by the salvage pathway. |
| inosine | A purine nucleoside that has hypoxanthine linked by the N9 nitrogen to the C1 carbon of ribose. It is an intermediate in the degradation of purines and purine nucleosides to uric acid and in pathways of purine salvage. It also occurs in the anticodon of certain transfer RNA molecules. (Dorland, 28th ed) |
| ribose 1-phosphate | RN given refers to (D)-isomer |
| Ribose | A pentose active in biological systems usually in its D-form. |
| xanthosine 5'-triphosphate | RN given refers to parent cpd |
| xanthine | A purine base found in most body tissues and fluids, certain plants, and some urinary calculi. It is an intermediate in the degradation of adenosine monophosphate to uric acid, being formed by oxidation of hypoxanthine. The methylated xanthine compounds caffeine, theobromine, and theophylline and their derivatives are used in medicine for their bronchodilator effects. (Dorland, 28th ed) |
