On a recent exam for my Biology of Cancer course, my professor asked us why 
sheep didn't shrink (or at least their wool) when they got wet.  I had no 
idea other than maybe some sort of lipid protection.  So I was interested 
in finding the answer, and I haven't been able to find it on the web or in 
the library.  I am curious to know why the wool doesn't shrink because when 
you buy a wool sweater and get it wet, it shrinks.  What is the difference? 
THANKS!
