Lignin is a complex polysaccharide (therefore a carbohydrate).

There are no amino acids, nitrogenous bases, or fatty acids-- therefore lignin must be a carbohydrate and have sexy glycosidic linkages.
Wikipedia says it so it must be true.

Lignin is a type of polymer found in the cell walls of plant cells that provides support and structure for the plant- it makes them rigid.
Acidified phloroglucinol is used as a stain for the detection of lignin. If lignin is present, it will turn a bright red colour.
Lignin is a complex organic polymer found in the cell walls of plants. It provides structural support to the plant cells and helps transport water through the plant. Lignin is responsible for the rigidity and strength of plant tissues.
To dissolve lignin organosolv from a powder into a solution, you can use a suitable solvent such as ethanol or acetone and heat the mixture gently while stirring to help dissolve the lignin. Once dissolved, you can filter the solution to remove any undissolved particles and obtain a clear lignin organosolv solution.
Lignin naturally falls into the functional group of aromatic compounds due to its complex structure composed mainly of phenylpropane units. Aromatic compounds contain a ring of atoms with alternating single and double bonds, which is a characteristic feature of lignin's chemical structure.
The source of lignin in the soil is dead plants.
One of the things that phyloroglucin contains is lignin.
Lignin is a biopolymer that gives support to vascular plants, and is thought to have evolved after aquatic plants took on land. many aquatic plants produce lignin or lignin-like polyphenols however. There is still debate on distinguishing terrestrial from aquatic plant lignin.

Kraft lignin is the form of lignin commonly used in paper making. It is a byproduct of the kraft pulping process that breaks down wood fibers to extract cellulose for paper production. Kraft lignin provides strength and structure to paper products.
