| lignin | <plant biology> Organic substance which act as a binder for the cellulose fibres in wood and certain plants and adds strength and stiffness to the cell walls. The chemical structure of lignin is composed of a complex polymer of phenylpropanoid subunits, laid down in the walls of plant cells such as xylem vessels and sclerenchyma. It imparts considerable strength to the wall and also protects it against degradation by microorganisms. It is also laid down as a defence reaction against pathogenic attack, as part of the hypersensitive response of plants. (14 Oct 1997) |

| lignin peroxidase | <enzyme> Requires h2o2; fungal enzyme degrades the lignin model cpd 1-(3',4'-diethoxyphenyl)-1,3-dihydroxy-(4-''-methoxyphenyl)propane (diarylpropropane); also catalyses the oxidation of veratryl alcohol to veratryl aldehyde in the presence of h2o2 Registry number: EC 1.11.1.- Synonym: diarylpropane oxygenase (26 Jun 1999) |
| lignin-forming peroxidase | <enzyme> Involved in polymerization of cinnamyl alcohols into lignin;amino acid sequence has been determined for tobacco enzyme Registry number: EC 1.11.1.- (26 Jun 1999) |
| ligninase | <enzyme> A haemoprotein from phanerochaete chrysosporium with a variety of lignin-degrading reactions, all dependent on hydrogen peroxide; incorporates molecular oxygen into the products Registry number: EC 1.14.99.- (26 Jun 1999) |

| lignin |
(L. lignum, wood) A group of high-molecular-weight amorphous materials, comprising polymers of phenylpropanoid compounds, giving strength to certain tissues. Wood is composed of lignified xylem cells (about 15 to 30% by weight).

| lignin |
A complex polymer that occurs in woody material of higher plants. It is highly resistant to chemical and enzymatic degradation. Lignin is composed of various intermolecular linkages between phenylpropanes and guaiacyl, syringyl, p-hydroxyphenyl, and biphenyl nuclei. ...

| lignin |
is a polymer of conferyl alcohol found in wood. Lignin may be oxidized to gave vanillin. Vanillin is used as a rubber strengthener, and in laboratories to precipitate proteins.
