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.

2024年12月27日 · 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.

2018年3月29日 · 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 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

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, ...

2008年1月1日 · Lignin is one of the most predominant biopolymers present in plants. Together with cellulose and hemicelluloses, lignin builds up the cell wall in an arrangement which is regulated on the nano-scale and results in lignin–carbohydrate network structures.

2018年1月24日 · 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.

2025年1月12日 · Lignin is a complex organic polymer found in plant cell walls that provides structural support. It is second only to cellulose in abundance and is crucial for plant growth and development. Lignin also plays a role in the transportation of water and nutrients within the plant.

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 ...

Lignin is a class of complex aromatic polymers particularly important in the formation of cell walls, especially in wood and bark. Lignin contributes to plant structure, support, and defense against pests and pathogens, but it also is an exciting and renewable polymer with a wide range of opportunities for biotechnology ( Ralph et al., 2019 ).
