cutin

[′kyüt·ən]
(biochemistry)
A mixture of fatty substances characteristically found in epidermal cell walls and in the cuticle of plant leaves and stems.

Cutin

 

the most important component of the cuticle of plants, secreted by the underlying epidermis.

The principal components of cutin are ω-oxymonocarboxylic acids, which contain 16 and 18 atoms of carbon in an un-branched chain and two or three hydroxyl groups. The cutin content in the epidermis varies greatly (from 0.8 percent, in birch leaves, to more than 15 percent, in agave leaves). Cutin’s resistance to external influences and its water-repellent properties account for its protective role: the cutinized epidermis of the plants protects them from water loss and penetration by microorganisms.
