Description | 4-{3-[(1E,3E,5E,8Z,10E,12R)-12-hydroxytetradeca-1,3,5,8,10-pentaen-1-yl]oxiran-2-yl}butanoic acid, also known as 5,6-epoxy,18R-hydroxy-7E,9E,11Z,14Z,16E-eicosapentaenoic acid, belongs to the class of organic compounds known as long-chain fatty alcohols. These are fatty alcohols that have an aliphatic tail of 13 to 21 carbon atoms. 4-{3-[(1E,3E,5E,8Z,10E,12R)-12-hydroxytetradeca-1,3,5,8,10-pentaen-1-yl]oxiran-2-yl}butanoic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). |
