Cutin is a waxy substance on plant surfaces that tends to make the surface waterproof and can protect leaves from dehydration and disease. It is an insoluble polymer that, embedded in waxes, forms the cuticle covering the epidermal cell walls in the aerial parts of higher plants. In desert plants, it forms the thick waxy coating outside the epidermis.
Suberin is a wax like fatty substance, occurring in cork cell walls and in or between other cells. On alkaline hydrolysis it yields chiefly suberic acid. Suberin is highly hydrophobic and its main function is to prevent water from penetrating the tissue.
