Cutin is one of two waxy polymers that are the main components of the plant cuticle, which covers all aerial surfaces of plants, the other being cutan. It is an insoluble substance with waterproof quality.
The molecule, cutin, which composes most of the cuticle matrix (40-80%), is composed primarily of fatty acid chains that are polymerized via carboxylic ester bonds. [4] [6] Research suggests that cutin plays a critical role in preventing pathogenic infections in plant systems. [7]
Cutin, a polyester polymer composed of inter-esterified omega hydroxy acids which are cross-linked by ester and epoxide bonds, is the best-known structural component of the cuticular membrane. [ 3 ] [ 4 ] The cuticle can also contain a non-saponifiable hydrocarbon polymer known as cutan . [ 5 ]
Suberins and lignins are considered covalently linked to lipids and carbohydrates, respectively, and lignin is covalently linked to suberin, and to a lesser extent, to cutin. [1] [2] [3] Suberin is a major constituent of cork, and is named after the cork oak, Quercus suber. Its main function is as a barrier to movement of water and solutes.
The other and better-known polymer is cutin. Cutan is believed to be a hydrocarbon polymer, whereas cutin is a polyester , but the structure and synthesis of cutan are not yet fully understood. Cutan is not present in as many plants as once thought; for instance it is absent in Ginkgo .

The Slab Boys Trilogy is a set of three plays by the Scottish playwright John Byrne.The trilogy was originally known as Paisley Patterns.The three plays which make up the trilogy are: The Slab Boys, Cuttin' a Rug, and Still Life.
Chemical configurations of the different monosaccharides (glucose and N-acetylglucosamine) and polysaccharides (chitin and cellulose) presented in Haworth projection. The structure of chitin was determined by Albert Hofmann in 1929.
