4-Methyl-2-oxovaleric acid Chemical Properties,Usage,Production

Occurrence

Reported found in banana, asparagus, cheese, white wine, cocoa, blue cheese and provolone cheese.

Uses

4-Methyl-2-oxovaleric acid is an intermediate in the metabolism of leucine and also used as flavoring agents.

Definition

ChEBI: A 2-oxo monocarboxylic acid that is pentanoic acid (valeric acid) substituted with a keto group at C-2 and a methyl group at C-4. A metabolite that has been found to accumulate in maple syrup urine disease.

in vivo

4-Methyl-2-oxopentanoic acid (4 mol/L; ICV; 1 h and 15 d) causes impairment of habitual memory and long-term memory in rats^[3]. 4-Methyl-2-oxopentanoic acid (400 μmol/kg/h; carotid arch injection; single dose injection 60 min) increases porcine skeletal muscle protein synthesis and plasma leucine levels^[4].

Animal Model:	Thirty-day-old rats were anesthetized with a mixture of ketamine and xylazine (HY-B0443)^[3]
Dosage:	4 mol/L, Administer 2 μL
Administration:	Intracerebroventricular injection (ICV); 1 h and 15 days
Result:	Increased TBARS levels, protein carbonyl content and DNA damage in the hippocampus, striatum and cerebral cortex. SOD activity in the hippocampus and striatum increased 1 hour after injection, and SOD activity in the striatum decreased 15 days later.

Animal Model:	Piglets were deprived of feed for 12-14 hours before infusion^[4]
Dosage:	400 μmol/kg
Administration:	Inject into the aortic arch; the initial injection dose is 148 μmol/kg in the first 10 minutes, and the continuous infusion dose is 400 μmol/kg
Result:	Increased phosphorylation of eukaryotic initiation factor (eIF) 4E binding protein-1 (4E-BP1) and eIF4G in skeletal muscle and increased the formation of active eIF4G×eIF4E complexes.
