Question

write note on oligosaccharides
​

Answer 1

Answer:

Oligosaccharides are formed when two or more monosaccharides join together by O-glycosidic bonds. Examples include sucrose, lactose and maltose. Specific enzymes are used to catalyze the glycosidic bonds in olgosaccharides and each sugar must be specific to each enzyme used for each new glycosidic bond.

Explanation:

Answer 2

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
