Negatively charged lipid
Did you know?
The phospholipids are amphiphilic. The hydrophilic end usually contains a negatively charged phosphate group, and the hydrophobic end usually consists of two "tails" that are long fatty acid residues. In aqueous solutions, phospholipids are driven by hydrophobic interactions, which result in the fatty acid tails aggregating to minimize interactions with th… WebOnce taken into endosomes, in which luminal pH is progressively acidified by V-ATPases pumps as endosomes mature, the ionizable lipid once again acquires a positive charge and the cationic lipid interacts with negatively charged phospholipids in the endosomal membrane, resulting in membrane detabilization and release of payload to cytosol (Fig ...
