bilayer; phospholipid membrane. In an aqueous environment phospholipids can form a two-layered "sandwich" with the hydrophobic lipid tails on the inside and the hydrophilic phosphate heads facing outward. These bilayers are the essential structure for building cell membranes.
A symmetrical two-layer structure formed by phospholipids in aqueous solution; the basic structure of all biomembranes. In a bilayer, the polar head groups are exposed to the aqueous medium, while the nonpolar hydrocarbon chains of the fatty acids are in the center.
the arrangement of phospholipid molecules in two parallel rows, in which the hydrophilic heads face outward & the hydrophobic tails face inward
A double layer of phospholipid molecules that provides the structure of the cell membrane. Formed naturally from the alignment of the two layers of lipids such that their hydrophobic tails point inward toward each other and their hydrophilic phosphate heads point outward into the watery environments inside and outside of the cell.
A symmetrical two-layer structure, found in all biomembranes, in which the polar head groups of phospholipids are exposed to the aqueous medium, while the nonpolar hydrocarbon chains of the fatty acids are in the center. ( Figure 5-30)
the main component of cellular membranes - phospholipids have a non-polar fatty acid chain at one end and a polar phosphate group at the other; this facilitates the formation of a double layer of phospholipids such that the non polar groups interact with each other and the polar groups interact with the cellular cytoplasm and interstitial fluid.
A double layer of phospholipid molecules arranged so that the hydrophobic "tails" lie sandwiched between the hydrophilic "heads." This bilayer forms the backbone of the plasma membrane.
