41. This family contains acyltransferases involved in phospholipid biosynthesis and proteins of unknown function. 42. They are surrounded by a phospholipid bilayer composed of several different lipid molecules. 43. This gene encodes the member 3 of the phospholipid -transporting ATPase 8B. 44. Each typically has a cell membrane formed of phospholipids , cytoplasm and a triploblastic. 45. Plasmalogen is the most abundant phospholipid in myelin. 46. Purified phospholipids are produced commercially and have found applications in nanotechnology and materials science. 47. Cholesterol has the ability to eliminate the liquid to solid phase transition in phospholipids . 48. Phosphoinositides are regarded as the most acidic phospholipids . 49. After binding to the phospholipid surface, annexin A5 assembles into a trimeric cluster. 50. Many cells maintain asymmetric distributions of phospholipids between their cytoplasmic and exoplasmic membrane leaflets.
