Cellulose microfibrils have an ordered structure and are synthesized at the plasma membrane, given characteristics of microfibrils;
a) Each microfibril is composed of an estimated 18 parallel chains of (1,4)-linked β-D-glucose chains tightly bonded to each other to form a crystalline microfibril
b) Microfibrils have hydrophilic surfaces, populated by polar –OH groups extending from the plane of the sugar rings
c) Microfibrils have hydrophobic surfaces, populated by nonpolar C–H groups populating the sides of stacked glucose chains
d) microfibril important for enzymatic attack by microbial cellulases, which dock onto the hydrophobic surface and remove one glucan chain at a time
Which of the following from given characteristics of microfibrils is incorrect?
