Partial depolymerization of genetically modified potato tuber periderm reveals intermolecular linkages in suberin polyester

Potato periderm suberin builds as a macromolecule from a glycerol - octadec-9-ene-1,18-dioic acid - glycerol backbone, linked in its periphery to polyaromatics through the glycerol - 18-hydroxyoctadec-9-enoic acid - ferulic acid connection.
