A phospholipid is a type of lipid molecule that is a major component of all cell membranes, forming the lipid bilayer. This structure consists of two fatty acid tails that are hydrophobic (water-repelling) and a phosphate group that is hydrophilic (water-attracting), allowing phospholipids to create a barrier between the inside and outside of the cell. Their unique properties enable them to play crucial roles in membrane fluidity, signaling, and the overall function of eukaryotic cells.
congrats on reading the definition of phospholipid. now let's actually learn it.
