Question

Role of oligosaccharides present in the cell membrane

Answer 1

Glycolipids are important for cell recognition, and are important for modulating the function of membrane proteins that act as receptors. Glycolipids are lipid molecules bound to oligosaccharides, generally present in the lipid bilayer. ... The head of the oligosaccharide serves as a binding partner in receptor activity.

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
