Question

composition of Suberin and cutien give short ans

Answer 1

Cutin and suberin consist of fatty acid derivatives, phenolic compounds, and glycerol. In most plants, cutin consists mainly of hydroxy- and epoxy-hydroxy fatty acids of 16 and 18 carbons as well as a very small portion of phenols. In contrast, suberin also contains very long-chain fatty acid derivatives, a high proportion of dicarboxylic acids, and a large fraction of phenols (Kolattukudy, 1981). The main components of suberin are largely defined to different subdomains in the polymer, a polyphenol domain that is part of the primary cell wall and an aliphatic domain close to the plasmalemma .
