Patent ID: 7811988

Claim:
A lipid mixture for preparing a synthetic surfactant, said lipid mixture comprising at least 95% by weight of phospholipids, said phospholipids comprising: 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) in an amount of at least 40% by weight; polyunsaturated phospholipids in an amount higher than 10% by weight, said polyunsaturated phospholipids selected from the group consisting of 1-palmitoyl-2-linoleyl-sn-glycero-3-phosphocholine (PLPC), 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine (PAPC), 1-stearoyl-2-arachidonoyl-sn-glycero-3-phosphocholine (SAPC), phosphatidylethanolamine isolated from egg (egg-PE) and a phospholipid mixture obtained by isolation from liver (liver-PL); and saturated or monounsaturated acidic phospholipids in an amount higher than 10% by weight; wherein all the amounts are calculated on the total weight of the lipid mixture.
