DescriptionGeosmin belongs to the class of organic compounds known as tertiary alcohols. Tertiary alcohols are compounds in which a hydroxy group, -OH, is attached to a saturated carbon atom R3COH (R not H ). Geosmin is an extremely weak basic (essentially neutral) compound (based on its pKa). Geosmin exists in both E. coli (prokaryote) and yeast (eukaryote).
