Modela nastanka ligninskega polimera

Abstract

V članku sta opisana dva modela nastanka ligninske makromolekule. Model naključnega povezovanja predpostavlja nastanek lignina s slučajnostnim povezovanjem fenolnih monomernih radikalov z ligninskim polimerom. Po modelu proteinskega usmerjanja proces ligninske polimerizacije v celoti vodijo specifični usmerjevalni proteini, ki vodijo nastanek posameznih vezi. Navedene so kritične sodbe in znanstvena mnenja o obeh modelih.

Secondary title:	Models of formation of lignin polymer
Secondary abstract:	In paper, two models of formation of lignin macromolecule are described. Random coupling model suggests lignin formation process through coupling of monomer radicals to growing lignin polymer in a near-random fashion. According to the dirigent protein model, process of lignin polymerization is fully controlled by specific dirigent proteins that direct formation of individual bonds. Critical judgements and scientific opinions of both models are given.
