can't see proteins, so how do you study them?
If you can't see it with the naked eye, you have to find ways to make it visible.
First, many cell proteins are not visible to the eye because they
are dissolved in the water that is inside and outside of cells.
You can often see these proteins if you change them so they no
longer dissolve in water. One way to make a protein dissolvable
is to change its structure (called denature)
so that it precipitates out of solution.
Heat denatures egg-white protein and makes it
