Lignin - Wikipedia
网页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.
Lignin | Definition, Function, Uses, & Facts | Britannica
网页2024年8月24日 · lignin, complex oxygen-containing 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 relatively few industrial uses other than as a fuel have been found.
A Brief Introduction to Lignin Structure | Lignin ...
网页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.
Lignins: Biosynthesis and Biological Functions in Plants
网页2018年1月24日 · 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, lodging resistance and the responses to a variety of biotic and abiotic stresses. In the present …
Lignin - an overview | ScienceDirect Topics
网页Lignin is a biopolymer that binds cellulose and hemicellulose fibers and provides stiffness to plants. Lignin is the second most abundant polymer after cellulose because 3 × 1011 metric tons of lignin is present worldwide, with yearly biosynthesis of approximately 2 × 10 11 metric tons. [1,2].
Lignins: Major Sources, Structure and Properties - ScienceDirect
网页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.
Lignins: Biosynthesis and Biological Functions in Plants
网页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.
