The major building blocks of lignin, called monolignols, are sinapyl and coniferyl alcohols, with minor amounts of p-coumaryl alcohol (Figure 14.22A). (...) Lignin formation involves the oxidative radical-mediated coupling of monolignols in the wall, catalyzed by peroxidases and laccases to form a random combinatorial polymer (Figure 14.22B).
