Question

You prepared an artificial membrane with equal parts phosphatidylcholine and sphingomyelin. What else do you need to add to induce lipid rafts

1) phosphatidylethanolamine

2) phosphatidylserine

3) phosphatidylinositol

4)cholesterol

5) sphingosine

Answer 1

Ans:-> lipid raft :- The plasma membrane of cell contain com bioration & Glycosphigo lips, cholestrol and protein receptor are organised in Glycoprotein lipid microdomain fermed as lipid safts" - lipids rofte influence the membrane - fludity and membrane protein traffecking - cholestrol and sphingomyelin are the Principal component of lipids saft in a cell and model membrane Answer for this question is - cholestrol" 7 > - cholestral found in sussounding bilage where liftrafts are enriched with sphingolipids- this is core sot. of plasma membrane. but phosphati- - ylcholine lonel decreases which is similar in cholin-containing. sphingo lipids are saturated with hydrocarbons and tightly packed is surrounding bilayen. et due to rigid nature of sterol group cholestrol partition into the lipidsaft, where the acylchain tends to more sigid and len in fluid. synnay - Cholestrol play a major reale to induce lipid rott. steral gp give roft parktion and acky chain provides szidity.
