1. Suberin A fatty acid polyester produced in the walls of the endodermis and in bark, where it renders the tissue impermeable to water and resistant to decay.

2. Suberin, a natural substance in Cork, works as a mold inhibitor and prevents Cork flooring from rotting, besides that it has natural insulation properties that can help reduce heating costs

3. Development of the suberin wall modifications correlates with the development of the aerenchyma and may play a role in preventing gas exchange between the root and the rhizosphere.

4. Bimolecular phenoxy radical coupling is involved in numerous biological processes, including lignin (), lignan (2, 3), and suberin biosynthesis in vascular plants, fruiting body development in fungi (), and insect cuticle melanization and sclerotization (), as well as in the formation of aphid pigments and algal cell wall polymers ().In contrast to the marked specificity observed for these
