DPPC, or 1,2-dipalmitoyl-sn-glycero-3-phosphocholine, represents a notable member within the family of semi-synthetic lipids. Derived from palmitic acid, DPPC is characterized by a distinctive molecular structure and has garnered attention for its unique properties in membrane protein research.

Applications in Membrane Protein Research:

• Bilayer Stability: DPPC's saturated acyl chains and phase transition behavior make it conducive to the formation of stable lipid bilayers. This stability is advantageous in mimicking the lipid environment of biological membranes.

• Model System for Biophysical Studies: DPPC is often employed as a model lipid in biophysical studies due to its well-defined behavior, making it valuable for investigating membrane properties and interactions.

• Drug Delivery Systems: Beyond membrane protein research, DPPC's stability and biocompatibility have led to its use in drug delivery systems, particularly in liposomal formulations.
