Lichenin , also known as lichenan or moss starch , is a complex glucan occurring in certain species of lichens . It can be extracted from Cetraria islandica (Iceland moss ).[1] [2]
Structure [ edit ]
Chemically, lichenin is a mixed-linkage glucan , consisting of repeating glucose units linked by β-1,3 and β-1,4 glycosidic bonds.[1]
It is an important carbohydrate for reindeers and northern flying squirrels , which eat the lichen Bryoria fremontii
It can be extracted by digesting Iceland moss in a cold, weak solution of carbonate of soda for some time, and then boiling. By this process the lichenin is dissolved and on cooling separates as a colorless jelly. Iodine imparts no color to it.[3]
Other uses of the name [ edit ]
In his 1960 novel Trouble with Lichen John Wyndham gives the name Lichenin to a biochemical extract of lichen used to extend life expectancy beyond 300 years.
