Abstract:
Disclosed are a phosphatidylcholine excellent in oxidation stability, in which the ratio of the total weight of palmitoyl-linoleoyl-glycerophosphocholine (PLPC) and palmitoyl-oleoyl-glycerophosphocholine (POPC) to the total weight of stearoyl-linoleoyl-glycerophosphocholine (SLPC) and stearoyl-oleoyl-glycerophosphocholine (SOPC) is 4.5 or less, the PLPC, POPC, SLPC and SOPC being molecular species constituting the phosphatidylcholine, and in which the electric conductivity of a 5 wt. % suspension of the phosphatidylcholine in distilled water is 100 .mu.S/cm or less; and a process for producing the same.
