 Sterculic acid as its triglyceride is present in sterculia oils and at low levels in kapok seed oil (~12%), cottonseed oil (~1%), and in the seeds of the tree "Sterculia foetida" (~65-78%).These acids are highly reactive but the cyclopropene ring is destroyed during refining and hydrogenation of the oils.They have attracted interest because they reduce levels of the enzyme stearoyl-CoA 9-desaturase (SCD), which catalyzes the biodesaturation of stearic acid to oleic acid.
