Question

when non polar molecules pass through the lipid bi layer . how does the hydrophobic  molecule  pass through without being dissolved by the hydrophobic region of the lipid bi layer?

anonymous · Answer

The hydrophobic molecules diffuse across hydrophobic region. The phospholipid is amphipathic. If this hydrophobic molecule dissolves or 'insert' in the membrane, it will interupt the phospholipid interaction.

anonymous · Answer

so your saying the hydrophobic molecule passes through without dissolving in the hydrophobic region of the lipid bilayer?

anonymous · Answer

yup. They just pass through the membrane. 

I wonder if this non-polar molecule can actually insert in the membrane other than membrane lipid. I might be outdated.

anonymous · Answer

also , do you know how does the  non-polar molecule pass through without being repelled by the hydrophilic heads

anonymous · Answer

this i'm not sure, but i know that the rate of diffusion depends on the solubility of a molecule  in oil.

anonymous · Answer

also, i don't think that non-polar molecule is repelled by hydrophilic head, it is just that they form weak bond which is easily broken.
