The acute toxicity of 1-butanol is relatively low, with oral LD50 values of 790–4,360 mg/kg (rat; comparable values for ethanol are 7,000–15,000 mg/kg). It is metabolized completely in vertebrates in a manner similar to ethanol: alcohol dehydrogenase converts 1-butanol to butyraldehyde; this is then converted to butyric acid by aldehyde dehydrogenase. Butyric acid can be fully metabolized to carbon dioxide and water by the β-oxidation pathway. In the rat, only 0.03… Webtert-Amyl alcohol (TAA) or 2-methylbutan-2-ol (2M2B), is a branched pentanol.. Historically TAA has been used an anesthetic and more recently used as a recreational drug. TAA is mostly a positive allosteric modulator for GABA A receptors in the same way as ethanol. The psychotropic effects of TAA and ethanol are similar, though distinct. Impact on …
