write a note on oligosaccharide and glycosidic bond
Answers
Answer:
Oligosaccharide is a carbohydrate polymers comprise three to ten monosaccharides, or, simple sugars. They were linked together mostly by O-glycosidic bond through condensation reaction between an anomeric carbon of a monosaccharide and the other. They can also form N-glycosidic linkages under certain atmosphere.
Answer:
They are
small carbohydrates which are formed
by condensation (a chemical reaction in
which two molecules combine to form
one molecule with loss of a small
molecule usually water) of 2-9
monosaccharides units are joined
together b glycosidic bond.
Depending upon the number of
monosaccharide molecules condensed to
form oligosaccharides, they can be:
Disaccharides (e.g. sucrose, maltose,
lactose, trehalose (present in
haemolymph of insects),
Trisaccharides(e.g. raffinose – made up
of glucose, fructose and galactose),
Tetrasaccharides (e.g. stachyose) et
