Maybe not "carbohydrate" exactly [Cn(H2O)n] , but nitrogen, carbon,
hydrogen, oxygen, close enough.

Proteins have a repeating N-C-C backbone, as is explained in any
college-level biology and chemistry text...

Just to throw a wrench into the works, would white blood cells also
contribute to the white color?

Take some chicken breast and throw it in the microwave for a couple of
minutes, notice the color... what do you see?  (Make sure it's
thoroughly cooked before eating!)
