From PMID:19846769 - "Structurally, suberin is a complex lipophilic polymer, containing a fatty acid-derived domain (aliphatic suberin) and a (poly)hydroxycinnamate domain (aromatic suberin). The aliphatic suberin is a 3D, glycerol-bridged polyester network, comprised primarily of omega-hydroxyacids and alhpa,omega-dicarboxylic acids, with chain lengths ranging from C-16 to C-32 (mainly C-18). They exist as discrete components between the plasmalemma and the primary cell wall matrix (2, 3, 5). The aromatic domain is principally composed of p-hydroxycinnamates (e.g., ferulate, p-coumarate, and sinapate) and their derivatives and possibly a low level of monolignols (4, 6)."
