Transfats and cell membranes -- do the cells repair the damage? Or are the molecules forever "mutated" ?
http://www.fi.edu/brain/fats.htm
Studies show that the trans fatty acids we eat do get incorporated into brain cell membranes, including the myelin sheath that insulates neurons. They replace the natural DHA in the membrane, which affects the electrical activity of the neuron.
Trans fatty acid molecules disrupt communication, setting the stage for cellular degeneration and diminished mental performance.
Normal fatty acids have a natural curve to their molecular shape. When they fit together in vast numbers, enough space still remains so that the membrane has the proper structure it needs to function at its best.
However, if these same fat molecules are changed by manufactured food processes, or if they are heated for long periods – as in deep frying – they mutate into a form rarely found in nature. Now their molecules are straighter, narrower, and no longer have their original curved shape.
Yeah, cells constantly do recycle their membranes, so eventually those phospholipids will get used in vesicles or such. Also, i don't think changing the shape of a few phospholipids will affect it that much, unless the entire plasma membrane is in a different shape phosphlipid, which would screw up the fluidity of the membrane.

Can I bring a pocketknife into Hong Kong?
I have a Smith and Wesson Homeland Security pocketknife, that is not spring operated, and not a gravity knife. It opens with one hand utilizing thumb pressure applied solely a thumb stud attached to the blade, and it has a mechanism that provides resistance which must be overcome in opening the blade.
It has a blade length of approximately 3 inches.
Will I be able to travel with it in my check-in luggage through U.S. Federal and Hong Kong Customs without too much trouble?
PS: I need to know this because I do not want to be prosecuted when I step off the plane.
So the answer, if you can you can, if you can't you can't, doesn't work in this case.
Yes it is permissible to carry it in your checked baggage.
