Absorption, Distribution and Excretion
It is readily absorbed from the gastrointestinal tract in man. Metabolism / Metabolites In contrast to valeric acid, isovaleric acid is ketogenic. ...Is metabolized by the liver to give two- and three-carbon fragments. The isopropyl fragment of isovaleric acid is readily converted to acetoacetate and is an efficient source of carbon atoms for fatty acid and cholesterol synthesis. Isovaleric acid ... has been identified in the fermentative organs of ruminant animals. Isovaleric acid is an intermediate in leucine metabolism. High blood concentrations of isovaleric acid occur in patients with the clinical disorder "isovaleric acidemia." This is a genetic defect of leucine metabolism in which the enzyme isovaleryl-coenzyme A dehydrogenase is inhibited or absent. The disease is characterized by episodic acidosis, slight mental retardation, and an unpleasant body odor. RATS RECEIVING LABELED ISOVALERIC ACID EXCRETED NONRADIOACTIVE ISOVALTHINE. Isovalerate given iv to normal rats was rapidly metabolized, with a 50% decr in plasma concn after 11 min, and this time was shortened to 5 min by the simultaneous admin of glycine. The hypoglycin metabolite methylenecyclopropylacetate-CoA inhibited butyryl-CoA dehydrogenase and isovaleryl-CoA dehydrogenase in liver. Gas chromatographic and mass spectrometric parameters of isovaleryl-beta-D-glucuronide, a new metabolite in the urine of patients with isovaleric acidemia, were presented. The significance of this metabolite for the detoxication of isovalerate in isovaleric acid media is discussed. |

Additional Infomation |
Isopentanoic acid is a colorless liquid with a penetrating odor. It is slightly soluble in water. It is corrosive to metals and to tissue.
Isovaleric acid is a C5, branched-chain saturated fatty acid. It has a role as a plant metabolite and a mammalian metabolite. It is a short-chain fatty acid, a methylbutyric acid and a branched-chain saturated fatty acid. It is a conjugate acid of an isovalerate. Isovaleric acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Isovaleric acid has been reported in Francisella tularensis, Artemisia macrocephala, and other organisms with data available. 3-Methylbutanoic acid is a metabolite found in or produced by Saccharomyces cerevisiae. Mechanism of Action (14)C-LABELED ISOVALERIC ACID ADMIN ORALLY TO RATS SHOWED ISOPROPYL GROUP WAS MORE EFFICIENTLY UTILIZED FOR CHOLESTEROL SYNTH THAN CARBOXYL GROUPS, & ALSO MORE EFFICIENTLY UTILIZED THAN FATTY ACID SYNTH. CLEAVAGE OF ACID INTO 2 FRAGMENTS OCCURS BEFORE CHOLESTEROL SYNTH. (14)C-LABELED ISOVALERIC ACID ADMIN ORALLY TO RATS APPEARS TO ENHANCE THE INCORPORATION OF CARBON DIOXIDE INTO CHOLESTEROL. All liver mitochondrial preparations were affected by 1.19 mM isovalerate. Isovaleryl CoA is a potent inhibitor of succinate:CoA ligase (SCL) with positive cooperativity and half-maximal inhibition at 273 +/-11 uM isovaleryl CoA. The investigators suggested that inhibition of the citric acid cycle at the SCL step may be a general mechanism of organic acid toxicity to mitochondria. |

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (24.48 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (24.48 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
