| In vitro study | Glutaric acid (GA) at concentrations of 1 and 2 mM is able to reduce TRAP measurement by up to 28% in a dose-dependent manner (β=0.77; P<0.001). Furthermore, a significantly inverse correlation is also verified between chemiluminescence and TRAP (β=0.81; P<0.001). Glutaric acid does not alter the activities of Cat and SOD, but strongly inhibits (up to 46%) the activity of GPx even at the lower concentration used (0.5 mM). It is observed that the metabolite inhibits this activity in a dose-dependent manner at concentrations as low as 0.05 mM. |

| biological activity | Glutaric acid (GA) is an attractive C5 dicarboxylic acid with a wide range of applications in the biochemical industry. |
| Use | Mainly used to produce glutaric anhydride The raw material for the production of glutaric anhydride is used as a synthetic resin and synthetic rubber. Initiator. |
| production method | industrially can be recovered from the by-product production of adipic acid. There are many methods for laboratory preparation. 1. Preparation of glutaric acid from γ-butyrolactone The γ-butyrolactone and potassium cyanide were heated to 190-195 ℃ and stirred for 2h. Cooling, adding concentrated hydrochloric acid to acidify to generate glutaric acid monoamide, and then heating and hydrolysis to obtain glutaric acid. Yield 71-75%. 2. Preparation of glutaric acid from dihydropyran Dihydropyran and 0.2N nitric acid are heated and dissolved in a boiling water bath, then cooled in an ice water bath, concentrated nitric acid is added, dihydropyran is hydrolyzed and nitrogen dioxide is escaped, when the temperature drops to 0 ℃, sodium nitrate is added and stirred strongly for 3 hours. No longer cooling, let the temperature rise to 25-30 ℃. Decompression evaporation and cooling to obtain glutaric acid with a yield of 70-75%. 3. Preparation of glutaric acid from glutaronitrile The glutaric acid is heated and refluxed with hydrochloric acid for 4 hours, and then evaporated to dryness. The residue contains glutaric acid and ammonium chloride, which is extracted with hot ether. The extract recovers the ether to obtain glutaric acid, which can be recrystallized with chloroform or benzene. 4. Cyclohexanone oxidation cyclohexanone by nitric acid oxidation production of adipic acid by glutaric acid. 5. Recovery of glutaric acid in the production of oxidized paraffin wax by by-product recovery method. The recovery method generally uses water extraction (or distillation, flash evaporation and steam distillation, etc.) and crystallization. 6. Cyclopentanone liquid phase oxidation method. 7. Dihydrofuran method. Glutaric acid is also prepared from 1, 3-propanediol in the laboratory. |
