Disc-shaped structures called bicelles

Researchers used neutron and X-ray scattering techniques to characterize disc-shaped structures, known as bicelles, that mimic cell membranes. The rim of the disc comprises a detergent (purple), while the disc’s center is made up of glycerophospholipids (green), sphingomyelin (blue) and cholesterol (gold).
