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.

The constituent acids of gymnosperm cutins
Phytochemistry, 1972Abstract The constituent cutin acids of selected species of gymnosperms, a lycopod and a fern have been determined by GLC-MS of the methyl ester trimethylsilyl ethers. A large number of novel cutin acids has been found. Of particular significance is the occurrence of 9,16-dihydroxyhexadecanoic acid in certain species.

Hydrolysis of Cutin by PET‐Hydrolases
Macromolecular Symposia, 2010AbstractFunctionalisation of synthetic polymers by using enzymes has been recently demonstrated. The major advantage of enzymes over chemical processes lies in their surface specific and endo‐wise mode of action. Surface hydrophilisation of PET with lipases and cutinases leads to a dramatic increase of the surfacial acid and hydroxyl group content ...

Building lipid barriers: biosynthesis of cutin and suberin
Trends in Plant Science, 2008Cutin and suberin are the polymer matrices for lipophilic cell wall barriers. These barriers control the fluxes of gases, water and solutes, and also play roles in protecting plants from biotic and abiotic stresses and in controlling plant morphology.

A cutin acid in Pinus sylvestris microspores
Phytochemistry, 1975Abstract Nonacosan-10-ol (0.7%) and the cutin acid, 9,16-dihydroxyhexadecanoic acid (0.3%) are present in Pinus sylvestris microspores. The pollen coat hence has some features in common with leaf cuticles.

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 ...

The constituent cutin acids of cranbury cuticle
Phytochemistry, 1972Abstract Purified cutin from cranberry ( Vaccinium macrocarpon , var. Howes) skin was selectively degraded, and the cutin acids, as methyl esters, separated by TLC into seven classes including monobasic acids, dibasic acids, monohydroxy monobasic acids, monohydroxy epoxymonobasic acids, vic -dihydroxy dibasic acids, dihydroxy monobasic acids and ...

Compositional Analysis of Cutin in Maize Leaves
Cold Spring Harbor ProtocolsThe cuticle is a lipid barrier that covers the air-exposed surfaces of plants. It consists of waxes and cutin, a cell wall–attached lipid polyester of oxygenated fatty acids and glycerol. Unlike waxes, cutin is insoluble in organic solvents, and its composition is typically studied by chemical depolymerization followed by monomer analysis by gas ...

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.
