WebWhat forces hold biological membranes together? Once lipid bilayers have formed, the membrane lipids are held together by weak noncovalent forces: van der Waals attractive forces are at work among the hydrocarbon tails, and ionic and hydrogen bonds form between the head groups and water. WebAdditionally, the two leaflets of biological membranes are asymmetric and divided into subdomains composed of specific proteins or lipids, allowing spatial segregation of biological processes associated with membranes.
