Technical Abstract: Ferulate polysaccharide esters in grasses enter into free-radical condensation reactions in the cell wall. By radical dimerization of ferulates, polysaccharide-polysaccharide cross-linking is effected. A range of diferulate isomers are produced, not solely the 5-5-coupled dimer which has been quantified historically. Both ferulates and diferulates enter lignification reactions and become intimately bound up with the lignin complex. Again, under-quantification is significant since it is not possible to release ferulate or diferulates from some of the structures. Overall, ferulates play a significant role in cell wall development and impact polysaccharide utilization in grasses.
