DSPC, or dipalmitoylphosphatidylcholine, is an indispensable phospholipid molecule that, due to its unique structure and function, serves as a crucial component of cell membranes. In the molecular structure of DSPC, the hydrophobic stearoyl chains act like sturdy building blocks of the cell membrane, intertwining with the hydrophobic tails of other phospholipid molecules to form a stable lipid bilayer structure. This structure provides the cell with a robust barrier, effectively protecting it from external harmful substances. At the same time, the stability of the lipid bilayer ensures the stability of the cell's internal environment, offering strong support for various cellular life activities. The hydrophilic glycerophosphocholine head of DSPC faces the external and internal environments of the cell, frequently interacting with water molecules and ions. Its presence allows DSPC to maintain a dynamic balance with water molecules and ions, thereby preserving the permeability and ionic balance of the cell membrane. This special arrangement enables DSPC to play a vital role within the cell membrane.
