Source sentences:
text: Surface charge of the liposome can be affected strongly by varying the hydrophilic head group of the lipid which are either zwitterionic [e.g., phosphatidylcholine (PC) and phosphatidylethanolamine (PE)], negatively charged [e.g., phosphatidylglycerol (PG)], or positively charged [e.g., 3-trimethylammonium-propane (TAP)] .
