Biopolyester Membranes of Plants: Cutin and Suberin
Science, 1980Cutin, a biopolyester composed of hydroxy and epoxy fatty acids, is the barrier between the aerial parts of higher plants and their environment. Suberin, a polymer containing aromatics and polyesters, functions as a barrier in underground parts, wound surfaces, and a variety of internal organs.

Cutin and suberin monomers are membrane perturbants
Journal of Colloid and Interface Science, 2004The interaction between cutin and suberin monomers, i.e., omega -hydroxylpalmitic acid, alpha, omega -hexadecanedioic acid, alpha, omega --hexadecanediol, 12-hydroxylstearic acid, and phospholipid vesicles biomimicking the lipid structure of plant cell membranes has been studied by optical and transmission electron microscopy, quasielastic light ...

Biochemistry and function of cutin and suberin
Canadian Journal of Botany, 1984Cutin, the structural component of plant cuticle, is a biopolyester composed of hydroxy- and hydroxyepoxy-fatty acids. The major monomers are a 16-hydroxy C16 acid, a 10,16-dihydroxy C16 acid together with its positional isomers, 18-hydroxy C18 acids, 18-hydroxy-9,10-epoxy C18 acids, and 9,10,18-trihydroxy C18 acids.

Investigation of suberinic acids-bonded particleboard
European Polymer Journal, 2019Abstract Birch outer bark and residual veneer shorts are one of the main leftovers from plywood production and have a high potential to be converted into value-added products. Birch (Betula pendula) outer bark contains up to 45% (dry basis) of suberin and has been recognized as a promising resource of suberinic acids (SA), where the bonding potential

Plant waxes consisting of very long-chain, relatively nonpolar lipid molecules are associated primarily with the cuticle which extends in a continuous sheet exterior to the walls of the epidermal cells of aerial tissues. In underground tissues, stems undergoing secondary growth, and wound healing sites, waxes are associated with the suberin matrix, a ...

The European pulp mills produce large amounts of bark as a by-product, about 4.3 Mt/y. Additional amounts are produced at sawmills. Birch outer bark contains about 35% of suberin. Suberin - a natural polyester - can be easily separated and depolymerized leading to the corresponding fatty acids, which are mostly straight chain, even numbered C16-C24 ...

Epoxyoctadecanoic acids in plant cutins and suberins
Phytochemistry, 1973Abstract Three C 18 epoxy acids occur in plant cutins and suberins. 9,10-Epoxy-18-hydroxyoctadecanoic acid is a common constituent of both cutins and suberins whilst 9,10-epoxy-18-hydroxyoctadec-12-enoic acid is also present in some cutins. 9,10-Epoxyoctadecane-1,18-dioic acid occurs more commonly in suberins.

Cutin and suberin are cell wall‐associated glycerolipid polymers that are specific to plants. Cutin forms the framework of the cuticle sealing the aerial epidermis, while suberin is present in the periderm of barks and underground organs. Suberised walls are also found in the root endodermis.
