Lipid	Na	[mβCD] (mM)b	${\chi }_s^0$c	ks × 103 (s−1)d	kf × 103 (s−1)e
DMPC	82	2.5	0.391 ± 0.002	2.38 ± 0.03	57.4 ± 1.2
SOPC	95	2.5	0.312 ± 0.004	8.2 ± 0.2	138.2 ± 3.9
DOPC	49	1.0	0.226 ± 0.004	0.98 ± 0.10	36.7 ± 0.8

The method of generating uncertainties in the fitting parameters is described in the Curve Fitting subsection.

^aThe number of replicate bilayers measured.

^bThe concentration of mβCD used (see the Materials and Methods).

^cFitting parameter corresponding to the initial mole fraction of the slow population of cholesterol.

^dFitting parameter corresponding to the rate constant for the depletion of the slow population of cholesterol.

^eFitting parameter corresponding to the rate constant for the depletion of the fast population of cholesterol.
