摘要：

The monoenoic methyl esters from numerous fats and oils which contained appreciable cis-9-hexadecenoic acid (cis-9-16:1) were isolated by liquid-solid chromatography on silver nitrate-silica gel. Analysis of the monoenes by packed and capillary column gas-liquid chromatography showed that significant amounts of cis-11-octadecenoic acid (cis-11-18:1) were present in all samples. The amount of cis-11-18:1 found in the monoenoic methyl esters increased proportionally to logarithmic increases in the cis-9-16:1 level. Most analyses reported in the literature also show this proportionality. This mathematical relationship suggests that chain elongation of cis-9-16:1 to cis-11-18:1 is a biosynthetic pathway operative in a wide variety of species. © 1968 American Oil Chemists' Society.
