1. Lignin

   Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily. Chemically, lignins are polymers made by cross-linking phenolic precursors.

1. lignin

   Lignin is a complex organic compound found in the cell walls of many plants, making them rigid and woody. It is the second most abundant natural polymer in the world, surpassed only by cellulose. Lignin helps to provide structural support for plants, allows for water transport in the vascular tissue, and plays a significant role in preventing decay and resisting pathogens.

1. Lignin

   Lignin or lignen is a complex chemical compound most commonly derived from wood, and an integral part of the secondary cell walls of plants and some algae. The term was introduced in 1819 by de Candolle and is derived from the Latin word lignum, meaning wood. It is one of the most abundant organic polymers on Earth, exceeded only by cellulose, employing 30% of non-fossil organic carbon, and constituting from a quarter to a third of the dry mass of wood. As a biopolymer, lignin is unusual because of its heterogeneity and lack of a defined primary structure. Its most commonly noted function is the support through strengthening of wood in trees. Global production of lignin is around 1.1 million metric tons per year and is used in a wide range of low volume, niche applications where the form but not the quality is important.

1. Lignin

   The most abundant natural aromatic organic polymer found in all vascular plants. Lignin together with cellulose and hemicellulose are the major cell wall components of the fibers of all wood and grass species. Lignin is composed of coniferyl, p-coumaryl, and sinapyl alcohols in varying ratios in different plant species. (From Merck Index, 11th ed)

Examples of lignin in a Sentence

1. Van Den Bosch:

   We add wood to a reactor and then we also need a catalyst, which is a specific material that will do the chemical reactions in the wood so it will selectively depolymerize our lignin material into chemicals; and then last but not least we also need solvent to extract the lignin out of the solid material and there we can use water for or also various kinds of bio-derived alcohols.
