Summary:
Above-ground epidermal surfaces of vascular plants are covered by a lipophilic layer known as the cuticle. The cuticle functions as a barrier to control the movement of gas, water and solute, as well as plant pathogens. Plant cuticles are composed of cutin and cuticular wax. Cutin is a polymer comprised of cutin monomers that are attached to each other by an ester linkage. Cutin monomers include C16 and C18 fatty acids and their derivatives, and glycerol. Among the fatty acid derivatives, ω-hydroxy-, polyhydroxy-, and epoxy-fatty acids are typical cutin monomers.

While α,ω-dicarboxylic acids are signatures of suberin (see suberin monomers biosynthesis), and are generally found only in trace level in cutin, they count for more than 50% of cutin monomers in Arabidopsis.

Among the enzymes characterized for the pathway, the Arabidopsis CYP86A8 and CYP94C1 both catalyze ω-hydroxylation of fatty acids. However they displayed distinct substrate specificities. CYP86A8 hydroxylates palmitate and stearate, but not expoxy fatty acids [Wellesen01], while CYP94C1 metabolized the latter more effectively [Kandel07]. A CYP P450 activity detected in soybean also had preference towards fatty acid epoxides [Blee93a].
