Collision cross sections obtained for the six [M+3H]³⁺ bradykinin conformations.

Conformationa	ccs (Å2)b	% abundance (source)c	% abundance (QE)d
A	269 (275e)	22.1%	1.8 ± 0.3%
B	285 (284f, 293e)	31.4%	16 ± 3%
C	305	30.8%	80 ± 2%
D	322	4.3%	< 1%
E	338	4.7%	< 1%
F	356	1.9%	< 1%

^aConformations from highest to lowest mobilities are shown in Figure 2.

^bCollision cross sections are reported using drift times from peak maxima in the overall arrival time distribution of [M+3H]³⁺ bradykinin ions.

^cPercent relative abundance (peak area) of each conformation relative to the total [M+3H]³⁺ source distribution.

^dPercent relative abundance (peak area) of each conformation relative to the total [M+3H]³⁺ distribution in the QE range.
