Lipid rafts are seen in?
c) Plasma membrane
Correct Answer - C
Ans. C. Plasma membrane.
- Lipid rafts are regions in plasma membrane that accumulate
Cholesterol and glycolipids (glycosphingolipids).
- So there regions are slightly thicker than other areas of plasma
- Because f distinct molecular composition of lipid rafts, they can
act us microcompartment within cells, giving the cell an additional
way to organize pathways.
- Involved in the regulation of signal transduction.
Types of lipid rafts:
- Planar lipid rafts (noncaveolar or glycolipid rafts)
- Continuous with plane of cell membrane (they are not invaginate).
- Specialized types of lipid rafts which are flask like invaginations of
- Produced where caveolin protein is present in lipid bilayer
