The suberin refers to the substances accumulated in the cell wall when the cell wall is thrombosed.The corky cell wall is difficult to aerate and permeate, which is determined by the nature of corky.
Although it has not been purified yet, it is considered to be a polymer containing long chain CH2 hydroxy fatty acid [CH2OH (CH2) 20COOH] or dicarboxylic acid (HOOC (CH2) 20COOH), which is quite different from what is commonly seen in fats, and has nothing to do with the composition of glycerol.

When the cork is oxidized with nitric acid, the cork acid (corky acid) C6H12 (COOH) 2 can be obtained. Of course, the cork fatty acid does not exist in the cork at the beginning.The cork has a great similarity with the cutin in terms of physiology and chemistry, but it is far weaker in terms of chemical treatment than the cutin, which is easy to be polymerized and separated, and easy to be alkaline hydrolyzed (alkaline hydrolysis).
