Phospholipids are described as amphipathic molecules, meaning they possess both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties. They consist of a glycerol backbone, two fatty acid tails, and a phosphate group, which contributes to their polar nature. This unique structure allows phospholipids to form bilayers, a fundamental component of cell membranes, providing structural integrity and facilitating the movement of substances in and out of cells.

What does fluid mosaic mean in reference to the plasma membrane?
A plasma membrane is described as mosaic because all the different components such as proteins and phospholipids, of varying shape and size, give the effect of the stones of a mosaic. It is described as fluid because these components can move freely within the membrane.
Is phospholipids are polarized molecules?
no
Are phospholipids proteins?
No, they are lipids.
What type of organic macro molecule shown below ia the main component of cell membranes?
Phospholipids
Why plasma membrane described as b ilayer?
The plasma membrane is made or phospholipids which contain a hydrophobic tail and a hydrophillic tail. In order to maintain stability the tails will attract the heads will be attracted to water which is found in both the cytosol and extracellular space. This causes a spontaneous formation of a bi-layer in which two phospholipids are stacked to prevent loss of fluid from the cell or vesicle.
The basic unit of the cell membrane is the?
Phospholipids.
Are the heads of phospholipids hydrophilic?
Yes, the heads of phospholipids are hydrophilic.
Is Hemoglobin a phospholipids?
hemoglobin is composed of long chanins called phospholipids
What is the subunit of phospholipids?
Phospholipids are a class of lipids, which are major components of cell membranes. The three subunits of phospholipids are phosphate, glycerol and fatty acids.
What does fluid mosaic mean in reference to the plasma membrane?
A plasma membrane is described as mosaic because all the different components such as proteins and phospholipids, of varying shape and size, give the effect of the stones of a mosaic. It is described as fluid because these components can move freely within the membrane.
Where in eukaryotic cells is phospholipids made?
