Abstract
We now know that in higher plants, cellulose is synthesised as crystallites ca. 2 nm across which can remain separate, aggregate loosely with xyloglucans to form 8-10 nm microfibrils, or coalesce into monocrystalline ca. 5 nm microfibrils as in the relatively pure textile celluloses. Using NMR, FTIR and electron diffraction we will determine the shape of the 5 nm microfibrils of cotton and flax cellulose, defining which crystal planes bound the Ibeta lattice and how the surface chains overlie them. The resulting model will be extended to the more complex microfibrils of primary- wall cellulose.
