Lignin is a collection of highly heterogeneous polymers derived from a handful of precursor lignols. Heterogeneity arises from the diversity and degree of crosslinking between these lignols.

Feb 21, 2025 · Lignin, complex organic polymer that, with cellulose, forms the chief constituent of wood. It is second to cellulose as the most abundant organic material on Earth, though it has found relatively few industrial uses other than as fuel.

Lignin is a biopolymer made up of three types of phenylpropane units linked by ether linkages and carbon–carbon interactions to generate three-dimensional network architecture. From: Bio-Based Flame-retardant Technology for Polymeric Materials, 2022

Mar 29, 2018 · Lignin is an alkyl-aromatic polymer found in the cell walls of terrestrial plants. Lignin provides structure and rigidity to plants, is a natural, highly effective barrier against microbial attack, and enables water and nutrient transport through plant tissues.

Lignin is one of the main components of plant cell wall and it is a natural phenolic polymer with high molecular weight, complex composition and structure. Lignin biosynthesis extensively contributes to plant growth, tissue/organ development, ...

In the present review, we systematically introduce the biosynthesis of lignin and its regulation by genetic modification and summarize the main biological functions of lignin in plants and their applications.

Jan 13, 2025 · The meaning of LIGNIN is an amorphous polymer related to cellulose that provides rigidity and together with cellulose forms the woody cell walls of plants and the cementing material between them.

This review focuses (A) on understanding what we mean with lignin, i.e., where it can be found and how it is produced in plants, devoting particular attention to the identity of lignols (including ferulates that are instrumental for integrating lignin with cell wall polysaccharides) and to the details of their coupling reactions and (B) on ...

1 day ago · Lignin, a complex and heterogeneous biopolymer found in plant cell walls, is required for structural stability and microbial resistance. As one of the most abundant organic polymers, lignin’s characteristics and stability are of great interest in materials research, bioengineering, and environmental science.

Apr 12, 2023 · Lignin can replace or augment its petroleum-based counterparts. And with the current trend for sustainable industries, both from the public and private sectors, lignin has the potential to be a building block of a low-carbon economy.
