FIGURE 5.

Fractional area expansion measured by GUV experiments (squares and triangles) compared with the values corresponding to the membrane-thinning measurement by x-ray (solid circles). The square and triangle data are the asymptotic values ΔA/A taken from the lower and upper limit measurements in Fig. 3, respectively; the error bars represent the standard deviations. The real area expansion effect of curcumin falls between the upper and lower limits. The curves are the results from the model as explained in the text.
