Phospholipids DSPE belong to the lipid family of biopolymers. Phospholipids consist of two fatty acids, a glycerol unit, a phosphate group, and a polar molecule. The phosphate groups and polar head regions of the molecule are hydrophilic (attracted to water), while the fatty acid tail is hydrophobic (repelled by water). When placed in water, the phospholipids Orient themselves into a double layer, where the non-polar tail region faces the inner region of the double layer. The polar head region faces outward and interacts with the water. Applications in drug release, nanotechnology and new materials research, cell culture. As well as ligand research, peptide synthesis support, grafted polymer compounds, new materials and pegylated modified functional coatings and other active compounds.
