cutin A polymer of long-chain fatty acids that forms the main constituent of the cuticle of epidermal plant cells. The cutin polymers are cross-linked forming a network, which is embedded in a matrix of waxes. The deposition of cutin (cutinization) reduces water loss by the plant and helps prevent the entry of pathogens. See also suberin.
cutin A complex biopolymer comprising a mixture of fatty-acid derivatives with water-proofing qualities found in the cuticle of plants.
cutin The complex mixture of fatty-acid derivatives with waterproofing qualities of which the cuticle of plants is composed.
