Figure 1.

Effect of an extraction with boiling SDS (2%, w/v) on the glycerol content of the wax and suberin fractions of green cotton fibers. A, Wax fraction; B, suberin fraction. After the SDS extraction, the fibers were dewaxed with organic solvents as usual. The remaining wax (A) and suberin (B) were then depolymerized by acid-catalyzed transesterification and the monomer concentration was determined as described in Methods. Gly, Glycerol; HCA, hydroxycinnamic acids; AA, alkanoic acids, ADA, α,ω-alkanedioic acids; HAA, ω-hydroxyalkanoic acids.
