A-Methylvaleric acid

An isomer of isocaproic acid, a-methylvaleric acid, CH3CH2CH2CH(C.l3)COOH, can be considered as acetic acid in which one hydrogen has been replace by a... [Pg.848]

The ether layer containing the bromomalonic acid is separated from the aqueous layer and the ether removed by distillation from a steam cone. The residual liquid is decarboxylated by refluxing for five hours in a 500-cc. round-bottomed flask on an oil bath heated to 130°. The bromo acid is then separated from the small amount of water and distilled. The material distilling at i25-i4o°/i8-2o mm. is a-bromo- -methylvaleric acid (Note 8). The yield is 150.5 g. (66.7 per cent of the theoretical amount). [Pg.62]

Dihydroxyacid dehydratase is involved in the biosynthesis of valine and isoleucine. L-a,/3-dihydroxyisovaleric acid and L-aj3-dihydroxy-/3-methylvaleric acid are dehydrated to form the a-keto acid precursors of valine and isoleucine. [Pg.255]

The 2,4-dinitrophenylhydrazone derivatives of a-ketoisovaleric acid and a-keto-jS-methylvaleric acid are separated from 2,4-dinitrophenylhydrazine by chromatography at room temperature on a Zorbax Cjg column (4.6 mm x 250 mm). Solvent A was 25% acetonitrile in water containing 0.1% triethyla-mine (v/v) and adjusted to pH 4.5 with acetic acid. Solvent B was acetonitrile. A linear gradient from 20 to 50% B was made within 20 minutes. The effluent was monitored at 254 nm. [Pg.255]
