Stereospecific analysis of soybeans and related species showed that there was little palmitic or stearic acid on the sn ‐2‐position, and the sn ‐1‐position is consistently richer in palmitic, stearic, and linolenic acids than the sn ‐3‐position. The sn ‐3‐position is enriched in oleic acid and the sn ‐2‐position with linoleic. Plots of the percentage of fatty acids on the glycerol positions vs. the percentage in the whole oil revealed a soybean variety that had a deviant distribution that is probably genetically controlled.
