Webb8 nov. 2024 · Lipid “rafts” are membrane microdomains composed of higher order lipids that have tight interaction with each other relative to the “sea” of liquid phase lipids known as bulk lipids. These rafts have been estimated to be 10-200 nm in size. Small rafts can merge to form large rafts through protein-protein and protein-lipid interactions. emmy macintyre https://jlhsolutionsinc.com

Until 1982, it was widely accepted that phospholipids and membrane proteins were randomly distributed in cell membranes, according to the Singer-Nicolson fluid mosaic model, published in 1972. However, membrane microdomains were postulated in the 1970s using biophysical approaches by Stier & Sackmann and Klausner & Karnovsky. These microdomains were attributed to the physical properties and organization of lipid mixtures by Stier & Sackmann and Israelachvi… WebbOrigins of the Lipid Raft Concept Biochemically, it is clear that lipids are sorted within the cell (6).
