The content by weight is from 39 to 45% of the mass of the cork.

suberin (45%) - main component of the cell walls, responsible for the elasticity of the cork;

Her team's carbon-capturing plant idea is based on a polymer called 'Suberin.

Her team’s carbon-capturing plant idea is based on a polymer called ‘Suberin.

Suberin thus plays an important role in the storage of carbon in the soil by plants.

Rapid changes go on around the developing split, and the cells immediately begin to produce suberin.

The presence of suberin, a complex mixture of fatty acids and heavy organic alcohols, renders cork impermeable to both liquids and gases.

Their chemical composition includes: suberin (45%), lignin (27%), cellulose and polysaccharides (12%), tannic acid (6%), wax (5%) and other substances (5%).

Suberin and ceroids contained in the cork cell walls makes it practically impermeable to liquids and gases.

Thanks to the suberin and ceroids contained in the cell walls, cork is practically impermeable to liquids and gases.

The presence of suberin (a complex mixture of fatty acids and heavy organic alcohol) renders cork impermeable to both liquids and gases.

Agrobacterium tumefaciens and Agrobacterium rhizogenes-Mediated Transformation of Potato and the Promoter Activity of a Suberin Gene by GUS Staining.

It is totally impermeable to liquids and practically impermeable to gases, thanks to the suberin and cerin present in the composition of cork cells.

Additional layers may be formed containing lignin in xylem cell walls, or containing suberin in cork cell walls.
