Abstract

Cellulose, a (1[RIGHTWARDS ARROW]4)-β-D-glucan, is the most abundant carbohydrate polymer in the biosphere, where it may account for 50% of the carbon. Cellulose has a structural and protective function in walls of plant cells and surfaces of other organisms. The insolubility and high tensile strength of cellulosic materials arises from the regular, extended, ribbon-like conformation of the individual molecules, their enormous lengths and their ability to aggregate into crystalline microfibrils.
