WebIn 1972, S. dessert apple Singer and Garth diplomatist developed the fluid-mosaic model of membrane structure. in line with this model, a membrane may be a double layer (bilayer) of proteins and phospholipids, and is fluid instead of solid. The lipoid bilayer forms a fluid “sea” during which specific proteins float like icebergs. WebThe hydrophilic heads of phospholipids in a membrane bilayer face outward, contacting the aqueous (watery) fluid both inside and outside the cell. Since water is a polar molecule, it readily forms electrostatic (charge-based) interactions with the phospholipid heads.
