Cutin
From Wikipedia, the free encyclopedia
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 major cuticle polymer, which is much more readily preserved in the fossil record,[1] is cutan. Cutin consists of omega hydroxy acids and their derivatives which are interlinked via ester bonds, forming a polyester polymer of indeterminate size.
There are two major monomer families of cutin, the C16 and C18 families. The C16 family consists mainly of 16-hydroxy palmitic acid and 9,16 or 10,16-dihydroxypalmitic acid. The C18 family consists mainly of 18-hydroxyoleic acid, 9,10-epoxy-18-hydroxystearic acid, and 9,10,18-trihydroxystearate.[2]
Cutin is sometimes confused with suberin.[citation needed]
