  1. * Mean values of different analytical data. The table contains the typical composition of the referred GPL, which may differ depending on its source and the employed analytical method. Information was extracted from the mentioned literature or from the analytical data sheets of the manufacturers.
  2. + Phosphatidylserine (PS) is also an important GPL found mostly in meat. A good source is bovine brain. This compound is not mentioned here, since it is not widely addressed in the present review.
