• 신진 대사

  Isobutyrates are hydrolysed to materials that are either normally in the diet or readily converted to such materials (Fassett, 1963a). Isobutyric acid occurs normally in the metabolism of valine, being converted to a propionyl group and entering into the glycogenic process (Fassett, 1963b). π-Octanol is largely oxidized in vivo; about 10% is excreted conjugated with glucuronic acid in rabbits. Isomeric octanols may be more highly conjugated; they may also be oxidized to the ketone or may be excreted unchanged (Williams, 1959).
