Alkylresorcinol
Alkylresorcinols (ARs), also known as resorcinolic lipids, are amphiphilic phenolic lipids characterised by a non-polar odd-numbered alkyl side chain with up to 27 carbon atoms attached to a polar resorcinol (1,3-dihydroxybenzene) ring. == Natural sources of alkylresorcinols == Alkylresorcinols are relatively rare in nature and are reported to be found in fungi, bacteria, and some lower and higher plants.
