Answer: All membrane lipids are amphipathic
Explanation:
The membrane lipid molecules are amphathic in nature which states that they are both hydrophobic and hydrophillic part. The lipid bi layer has been found tot be the most widely found in cell structure.
The structure is made of phosphorus and lipids and hence called as phospholipids.
The amphipathic nature of the lipids allows it to assemble spontaneously into bi layers even under the artificial conditions.
hence, all the lipids in the cell membrane or membranes are amphipathic in nature.
