Web16 sep. 2024 · All of the lipid molecules in cell membranes are amphipathic (or amphiphilic)—that is, they have a hydrophilic (“water-loving”) or polar end and a hydrophobic (“water-fearing”) or nonpolar end. The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails. Web7 apr. 2024 · Phospholipids are important in membranes (phospholipid membrane) because of their amphipathic nature (containing both hydrophobic and hydrophilic groups); they form a two-layer structure called the lipid bilayer, with the polar head facing out on each surface to interact with water and the neutral "tails" driven inward and pointing toward one another. mapforsyth
