http://amigo.geneontology.org/amigo/term/GO:0045121 Web摘要： Phase coexistence and domain formation in lipid bilayers are intriguing phenomena and play essential roles in many cell functions. In particular, coexistence of liquid-ordered and liquid-disordered phases in membranes of ternary lipid composition has drawn great attention, as it underlies the concept of ''lipid rafts'' in cell membranes.
