Flip  Flop  means  exchange  of  molecules  from  onse  monolayer  with  those  in  the  monolayer  on  the  other side.  However  phospholipid  bilayer  has  fluid  property  but  no  evidence  of  flip  flop  mechanism  for  protein molecule  Rotational  diffusion  and  lateral  diffusion  of  protein  and  lipids  is  possible  in  membrane.  Absence  of flip  flop  movement  detected  by  electro  spin  resonance  (ESR)  spectroscopy.

Relative to the lateral movement of the phospholipid molecules, there is very little exchange between the two halves of the bilayer. This minimal exchange, or flip flopaction, allows asymmetric distribution of phospholipids. ... In this model, the membrane is a mosaic of proteins embedded in a fluid phospholipid bilayer.
