Suberin

 

a substance secreted by the cells of integumental plant tissues; it infiltrates the cell walls, resulting in their suberi-zation. Chemically, suberin is a glyceride of phellonic acid, CH3(CH2)19CH(OH)COOH, and suberic acid, COOH(CH2)6-COOH. It is closely related to cutin, but is much less common.
