:Lipid monomers ( like palmitate ) can be part of polymers, like cutin, cutan, and suberin.
2.
Evidence that cutan is a hydrocarbon polymer comes from the fact that its flash pyrolysis products are a characteristic homologous series of paired alkanes and alkenes ( Nip " et al . " 1986)
3.
Cutan was first detected as a non-saponifiable component, resistant to de-esterification by alkaline hydrolysis, that increases in amount in cuticles of some species such as " Clivia miniata " as they reach maturity, apparently replacing the cutin secreted in the early stages of cuticle development ( Schmidt and Sch�nherr, 1982 ).
