1) Complete acid hydrolysis yields only D-glucose.
2) Controlled acid hydrolysis gives cellobiose.
▪ Arrangement of cellulose in the cell wall:
The strong properties of cellulose are due to the tendency of the individual
chains to form micro-fibrils through inter- and intra-molecular hydrogen bonding
to give a highly ordered structure. The multiple hydroxyl groups on the glucose
from one chain form hydrogen bonds with oxygen atoms on the same or on a
neighbor chain, holding the chains firmly together side-by-side and
forming microfibrils with high tensile strength. This confers tensile strength
in cell walls.
The micro-fibrils associate in a similar manner to give bundle, known as
macro-fibril. The cell wall consists of macro-fibrils arranged in a certain manner
