Adipocyte lipid-binding protein function

The blue netlike surface in Plate 2 is also a contour map of a three-dimensional function. It represents a surface on which the electron density p(x,y,z) of adipocyte lipid binding protein (ALBP) is constant. Imagine that the net encloses 98% (or some specified value) of the protein s electron density, and so the net is in essence an image of the protein s surface.
