Small-angle scattering is used to investigate a typical glycolipid micelle structure in conjunction with NMR determination of sugar cycle conformation. It is shown that the ellipsoidal shape of the micelle originates from two constraints: sugar rings perpendicular to the interface induce a limited area at the chain-head interface. Together with the bulky hydrated heads, this imposes an ellipsoidal shape.
