isoamyl alcohol
isopentanol
 
Notes:
Major component of fusel oil. A common constit. of plant oils, free and as esters. Present in many wines and spirits. Flavouring agent Isopentanol or Isoamyl alcohol is one of several isomers of amyl alcohol. It is a by-product of gut microbial fermentation (PMID: 17452087). It can be produced by 3-methylbutanal reductase (EC 1.1.1.265) from 3 methylbutanal. Isoamyl alcohol is the major higher chain alcohol in alcoholic beverages and is present in cider, mead, beer, wine, and spirits to varying degrees, being obtained by the fermentation of starches. Isopentanol has been shown to induce expression of CYP3A and CYP2E1 in human liver (PMID: 7574728)
