2. Glycolipid
 Glycolipids are glycoconjugates of lipids.
 The term glycolipid designates any compound
containing one or more monosaccharide residues
bound by a glycosidic linkage .
 It is a structural lipid .

3. They are generally found on the extracellular
face of eukaryotic cellular membrane.

4. Synthesis Of Glycolipid
Synthesis of glycolipids occurs with the help of
enzymes that sequentially add sugars to the lipid.

5. Types of Glycolipid
1. Cerebrosides-Cerebroside (from cerebro=brain)
are glycolipids that are found primarily in the
brain and peripheral (other areas of the body)
nervous tissue.
Function:
Provide protective coating to each
nerve and act as insulator.

6. Types of Lipid
2. Gangliosides- These glycolipids
(glycosphingolipids) are neutral (uncharged). The
gangliosides are acidic in pH and they are the more
complex of the glycolipids.

7. Type of Lipid
3. Sulfoglycosphingolipids-These cerebrosides are
also called sulfatides, They are simply cerebrosides
with a sulfate residue on the sugar portion of
glycolipid.
Ocurrance:
this particular lipid is found primarily in
the medulated nerve fibres.

8. Degradation of Glycolipid
lipids are required to be broken down,
enzymes in the lysosome of the cell help to remove
the sugar subunits.

9. Metabolism of Glycolipid in
Human
 The glycolipids are type of lipids that is utilised by
the human as well as other forms of life.
 Glycolipids are derivatives of ceramides.
 Glycolipids are simply fats that are bonded to
sugars.

10. Functions of Glycolipid
 The glycolipids are an essential part of cell
membranes.
 Glycolipids also help determine the blood group of
an individual.
 Glycolipids act as receptors at the surface of the
red blood cell.
 some viruses, bacteria (eg., cholera) use glycolipids
on their cell surface as well. This helps the immune
system destroy and clear the pathogen from the
body.

11. Functions of Glycolipid
 It provide energy.
• The antigens which determine blood types
belong glycolipids.
