Contribution of thermal transitions to the thermally induced variations in Ejl CD spectrum at 203 and 224 nm derived by equation (1)

		ΔΘi • 10−3 (dg dmol−1 cm2)
Choline (mM)	Tm °C	λ203	λ224
0	42.9	−5.07 + 0.035 • ta	−0.6
	48.0	—	−3.9
20	40.4	−4.7 + 0.035 • t	—
	50.2	—	0.6
	55.2	—	−7.3

^a The ellipticity change at 203 nm is a function of temperature due to the temperature dependence of Θ₂₀₃ after the thermal transition.
