DSPE-PEG-CH2COOH is a polyethylene glycol (PEG) modified phospholipid, commonly used in pharmaceutical research and development. The structure of DSPE-PEG-CH2COOH comprises of three functional groups, namely the hydrophobic alkyl chain, the hydrophilic PEG chain, and the carboxylic acid group. The hydrophobic alkyl chain is responsible for the incorporation of the molecule into the lipid bilayer, while the hydrophilic PEG chain provides a steric barrier that prevents aggregation and enhances stability. The carboxylic acid group provides an anchor point for chemical conjugation with other molecules, such as proteins or drugs.

DSPE-PEG-CH2COOH has gained significant attention in pharmaceutical research and development due to its unique properties, which make it an ideal candidate for drug delivery systems. The PEG chain increases the circulation time of the drug by reducing clearance by the immune system, while the carboxylic acid group allows for site-specific targeting of the drug to a particular tissue or organ. Additionally, the hydrophobic alkyl chain enables the incorporation of the drug into lipid-based drug delivery systems, such as liposomes, micelles, and lipid nanoparticles.

DSPE-PEG-CH2COOH is a versatile molecule with various functional groups that make it an ideal candidate for drug delivery systems. Its incorporation into pharmaceutical research and development has led to the development of novel drug delivery systems with enhanced efficacy and reduced toxicity, thereby improving patient outcomes.
