High temperature and phospholipids

Post by Cally » Wed Jan 17, 2007 7:25 pm

What happens if you increase the temperature? This is with reference to cell membranes, I know there are proteins within the membrane which are denatured. I am not quite sure what happens to the lipids? I have an idea of the structure and how the phospholipids are created but not sure what happen in high temp. Can someone explain to me please?

I am sorry if this has been asked before - if it has been asked, please direct me to the thread.
Thanks.

Think of butter in a frying pan...

Butter melts, is that what happens to the phospholipids? I don't mean to be ignorant. But I am doing self study so only have my text book to refer to. Do the bonds break?

It does not melt, but fluidity increases, so the movements inside the membrane are faster, and if you keep heating too much you might disrupt the membrane (and as well do plenty of other things to the sugar and proteins)
