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. [B.eseken & Hoagland Rec Trav Chim, Pays Bas 46 632 1927, Ahmad et al. J Am Chem Soc 70 3391 1948, IR: Rao & Daubert J Am Chem Soc 70 1102 1948.]
