It is related to cutin and suberin. Its preservation potential is much greater than that of cutin. Compounds which are more resistant to decay, like lignin or cutin, are considered recalcitrant. The purpose of cutin is to assist the plant to retain water. Leaves appear to be waxy therefore cutin is present. There are two major monomer families of cutin, the C16 and C18 families. They include cutinase, which hydrolyses cutin, facilitating fungus penetration through the cuticle. The systematic name of this enzyme class is cutin hydrolase. Plant cuticle is more prone to preservation if it contains cutan, rather than cutin. Alfredo Gamalo became the newly elected mayor while Sinforiano Cutin was reelected as vice mayor. Cell walls of the epidermis may contain cutin. The other and better-known polymer is cutin. Only the epidermal cells of plants synthesize cutin.
