👉 Lignins are a class of hydrocarbons that exhibit remarkable structural and functional properties. They are also known as lignans or lignanoids, which are organic compounds with the structure CH2(OH)n, where n is an integer. These structures are responsible for the characteristic chemical behavior of lignin, including its ability to form complex structures with cellulose fibers, which gives it a distinctive color and texture. Lignins can be found in a variety of plant species, including trees (
