E Correct answer
Explanation

α-Parinaric acid occurs naturally in the seeds of the makita tree. Both the alpha and beta (all trans) isomers of parinaric acid are used as molecular probes of lipid-lipid interactions by monitoring phase transitions in bilayer lipid membranes. α-Parinaric acid was shown to integrate normally into the phospholipid bilayer of mammalian cells.
