The acid is typically found together with other hydroxylated fatty acids, such as densipolic, auricolic, ricinoleic, etc.{{cite journal |last1=Salywon |first1=Andrew M. |last2=Dierig |first2=David A. |last3=Rebman |first3=Jon P. |last4=de Rodríguez |first4=Diana Jasso |title=Evaluation of new Lesquerella and Physaria (Brassicaceae) oilseed germplasm |journal=American Journal of Botany |date=2005 |volume=92 |issue=1 |pages=53–62 |doi=10.3732/ajb.92.1.53 |url=https://bsapubs.onlinelibrary.wiley.com/doi/full/10.3732/ajb.92.1.53 |access-date=4 April 2025 |language=en |issn=1537-2197|url-access=subscription }}
This compound has the R configuration at the alcohol-bearing stereocenter, and it is of the Z configuration at the olefin. Lesquerolic acid is chemically similar to ricinoleic acid, but with two additional carbons at the carboxyl end of the carbon chain.{{cite web
