Disulfides & organelles

[Louis Hom]

So, as far as I know, the cytoplasm is a reducing environment, so that the
tendency is for cysteins to be found in the reduced state.  In contrast, the
extracellular environment favors disulfide formation (I hope I'm right so
far). 
	So my question is, is it generally true that you'd expect to see
disulfide formation in structures/organelles that are topologically
equivalent to the outside of the cell?
