Illustrated Glossary of Organic Chemistry
Oligo
saccharide
:
A
molecule
containing between two and ten
monosaccharides
. When the oligo
saccharide
contains two
monosaccharides
it is a
disaccharide
. When the oligo
saccharide
contains more than ten
monosaccharides
it is a
polysaccharide
.
Lactose
contains two
monosaccharides
(
glucose
and
galactose
), so it is both a
disaccharide
and an oligo
saccharide
.
Cellulose
is a
polysaccharide
because it contains thousands of
glucose
subunits in each
cellulose
molecule
.
