Effect of solvents on cell membrane

Post by Jubijezza » Thu Dec 01, 2005 3:36 pm

Hello. I am new. Could anyone give me any help as to what the effects on the cell membrane are, when it is exposed to solvent..? I guess it becomes more permeable but I don't know why. What exactly happens to the phospholipids and proteins? Thanks. :shock:

Well, remembering my chemistry lessons I'm going to have to assume that by a solvent you mean something that will dissolve the membrane (solute). Therefore it would destroy the membrane.

I guess it would depend on the solvent. But i don't how it can affect the membrane, except for inactivating proteins...

If you added NaCl to your medium, it would dissolve into Na+ and Cl-, the increased concentration of Na would cause it to flow into the cell, and in a sense it is more permeable because more is flowing in...but the number of open channels where it flow in would be simply the passive channels and that doesn't really change so I'd say it doesn't really affect permeability, unless it was some sort of messenger that binds to receptors opening their channels.
