| | TRANS-11-OCTADECENOIC ACID Usage And Synthesis |
| Uses | Vaccenic Acid is a fatty acid found in Artemia salina that shows antimicrobial activity against a variety of microorganisms except Escherichia coli, Micrococcus luteus and Salmonella enteritidis. | | Definition | ChEBI: Vaccenic acid is an octadecenoic acid having a double bond at position 11; and which can occur in cis- or trans- configurations. It is an octadecenoic acid and a straight-chain fatty acid. It is a conjugate acid of a vaccenate(1-). | | Purification Methods | Crystallise the acid from acetone (m 45-45.5o) or aqueous MeOH (m 43.5-43.7o). The methyl ester has b 174-175o/5mm.
