Abstract
The metabolic fate ofcis-positional isomers of octadecenoates has been compared to that of naturally occurring oleic acid (cis-Δ9). Radioactive mixtures of tritium-labeled positional octadecenoate isomer and oleic acid-10-14C were administered to laying hens, and their eggs were analyzed for the isotopic ratios (3H/14C) incorporated into total egg lipid, triglycerides, and phospholipids. Variations in the isotopic ratios indicated the comparative metabolic utilization ofcis-positional isomers Δ8 through Δ12. Incorporation into egg lipid fractions is as follows: triglycerides: Δ9>Δ8, Δ9>Δ10, Δ9>Δ11, Δ9>12; phospholipid: Δ9>Δ8, Δ9>Δ10, Δ9<Δ11, Δ9<Δ12.
