## Abstract lβ^14^CβTransβ11βoctadecenoic acid was obtained in 60% overall yield by incubating 1β^14^C βlinoleic acid with sheep rumen microorganisms. The product, purified in the form of the methyl ester by silver nitrate chromatography, contained small amounts of related positional isomere as the
Elaidic acid, C 18 H 34 O 2 , has an essentially linear alkyl chain. The double bond is twisted across the mean direction of the alkyl chain in a skew 0 , trans, skew conformation. In the crystal structure, the molecules form centrosymmetric O-HΓ Γ ΓO hydrogen-bonded dimers (OΓ Γ ΓO = 2.684 A Λ).
