Figure 8

Order parameters (Saxis2) describing the degree of spatial restriction of the C3 symmetric axis for methyl groups in the α- and β-chains in the absence (panels a and c, respectively) and presence (panels b and d, respectively) of IHP. The uncertainties in Saxis2 for most methyl groups were ~0.01, and the maximal uncertainty was ~0.02. The Ala, Leu, Met, Thr, and Val methyls are colored magenta, red, green, light blue, and black, respectively. The pro-R and pro-S methyl groups for Val and Leu are represented with empty and filled circles, respectively. Reprinted with permission from ref. 74. Copyright 2013 American Chemical Society.
