Fluidity buffer present in cell membrane is
Stearic acid
Palmitic acid
Cholesterol
Linoleic acid
Membrane fluidity
Membrane fluidity changes with temperature Transition temperature (Tm)
“More is the Tm,less is the fluidity”
Cholesterol-Fluidity buffer
Saturated FAs
increase Tm and decrease fluidity Unsaturated FAs
decrease Tm and increase fluidity
