Substrate preference and kinetic properties of Medicago CCR2 differ from those of previously characterized CCRs. WebThioacidolysis, that is, solvolysis in dioxane-ethanethiol with boron trifluoride etherate, is an acid-catalyzed reaction which results in the depolymerization of lignins. The method may …
WebNov 1, 2024 · The lower thioacidolysis yield observed for the mature outer pericarp richer in H lignin units can be related to the higher proportion of resistant interunit bonds. These results suggest that after 450°DAF and in the outer pericarp a change in lignin structure occurs which consists in a higher frequency of resistant interunit linkages.
