Chemical Information
FooDB Namealpha-Hydroxyisobutyric acid
DescriptionAlpha-Hydroxyisobutyric acid is a metabolite of methyl tert-butyl ether (MTBE). MTBE may be obtained through environmental exposure. MTBE is rapidly eliminated from the body, mainly through expired air as the unchanged compound. MTBE is to some extent metabolised to t-butyl alcohol (TBA) and formaldehyde and oxidised to 2-methyl-1,2-propanediol and a-hydroxy isobuturic acid. Alpha-Hydroxyisobutyric acid has been used as an arial bactericide. [HMDB]
