(a) Matrix and (b) domain lipid. Yellow Martini “beads” are assigned scattering length 4.152 fm, while cyan tail beads are assigned −3.332 fm, providing contrast between the matrix and domain lipids. Choline (blue), phosphate (gold), and glycerol (pink) are assigned scattering lengths of −5.158, 26.72, and 18.888 fm, respectively.
