What is not true about liposomes?
Correct answer: A. They are lipid vesicles with their polar heads of phospholipids on the inner and hydrophobic tails on the outer side
- A. They are lipid vesicles with their polar heads of phospholipids on the inner and hydrophobic tails on the outer side
- B. They are bilayered spherical bodies
- C. They can easily cross the lipid bilayer
- D. They can be used in drug delivery system
Explanation
The heads (the phospho part) are polar while the tails (the lipid part) are non-polar. The heads, which form the outer and inner linings, are "hydrophilic" (water loving) while the tails that face the interior of the cell membrane are "hydrophobic" (water fearing).
