This model shows 9 glucose units joined by alternating β (beta) 1-4 bonds.

This forms a flat ribbon-like strand which is the basis for the cellulose microfibril.

Move the molecule end on to see this .. Zoom in on the middle section .. and .. back to original position.

Every other glucose unit is effectively the opposite way up, as they are in cellobiose. This can be seen when the carbon 6 and associated groups are highlighted.

Cellulose forms microfibrils with many such strand running parallel to one another, stabilised by hydrogen bonds which extend side ways between strands, as well as betweeen glucose units in each strand. Show ... hide H bonds within the strand.
