Lignin cas

Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. Chemically, lignins are polymers made by cross-linking phenolic precursors. Lignin was first mentioned in by the Swiss botanist A. It is one of the most abundant organic polymers on Earth , exceeded only by cellulose and chitin. Lignin is present in red algae , which suggest that the common ancestor of plants and red algae also synthesised lignin. This finding also suggests that the original function of lignin was structural as it plays this role in the red alga Calliarthron , where it supports joints between calcified segments. The composition of lignin varies from species to species.
