Phospholipids
Phospholipids are fat derivatives in which one fatty acid has been replaced by a phosphate group and one of several nitrogen-containing molecules.
Example: Phosphatidyl ethanolamine (also known as cephalin) ...
Phospholipids
lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see glycerophosphates) or sphingosine (sphingolipids).
Phospholipids are a class of lipids, and a major component of all biological membranes, along with glycolipids, cholesterol and proteins.
Phospholipid
Two schematic representations of a phospholipid.
Phospholipids are formed from four components: fatty acids, a negatively charged phosphate group, an alcohol and a backbone.

Definition of phospholipids : ...
phospholipids Asymmetrical lipid molecules with a hydrophilic head and a hydrophobic tail. Lipids with a phosphate group in place of one of the three fatty acid chains. Phospholipids are the building blocks of cellular membranes.
Phospholipids and glycolipids are important structural components of cell membranes. Phospholipids, shown in Figure 16, are modified so that a phosphate group (PO4-) is added to one of the fatty acids.
Phospholipid. A class of lipid molecules in which a phos- phate group is linked to glycerol and two fatty acyl groups. A chief component of biological membranes. (See Inositol phospholipid.) ...
Phospholipids
Most of the lipids in a membrane are phospholipids.
Phospholipids contain glycerol, two fatty acids, and a phosphate group. The phosphate group is polar (hydrophilic), enabling it to interact with water.
Phospholipids Important constituents of membranes and composed of three components: a backbone (usually glycerol or sphingosine), two fatty acid chains, and a phosphorylated alcohol.
Phospholipids have a strong affinity for other phospholipids, leading to self assembly.

phospholipid - the major category of lipid molecules used to construct biological membranes. Generally composed of two fatty acids linked through glycerol phosphate to one of a variety of polar groups.
phospholipid A type of lipid molecule occurring in a bilayer in biological membranes; a lipid with two fatty acids and a phosphate group attached to glycerol.
Within the phospholipid bilayer of the plasma membrane, many diverse proteins are embedded, while other proteins simply adhere to the surfaces of the bilayer.

Many Archaea make Ins and use it as a component of diphytanyl membrane phospholipids and the thermoprotective solute di-L-Ins-1,1´-phosphate. Few bacteria make Ins or use it, other than as a carbon source.
The plasma membrane is constituted by a phospholipidic bi-layer with proteins incrusted through it from outside to inside.
Cell Membrane: Every cell is enclosed in a membrane, a double layer of phospholipids (lipid bilayer).
Remind them of the good Îol selectively permeable membrane (the phospholipid bilayer) and how the hydrophobic tails are responsible for making the ion gradient possible. Maintaining this ion gradient is essential to life. 3.
HIV is an enveloped RNA virus: As HIV buds out of the host cell during replication, it acquires a phospholipid envelope. Protruding from the envelope are peg-like structures that the viral RNA encodes.
Scientists describe the organization of the phospholipids and proteins with the fluid mosaic model. That model shows that the phospholipids are in a shape like a head and a tail.
