The polarity of the phospholipid makes it ideal for a building block of cell membranes.
Explanation:
There is the tails which are hydrophobic (water fearing) and the heads which are hydrophilic (water loving). These properties of phospholipids allow the tails to go towards eachother and heads to face the water which maintains a solid structure allowing certain materials to pass through.
Phospholipids are organic compounds that consist of two fatty acid hydrophobic tails and a phosphate hydrophilic head.
These properties help in the regulation of the cellular processes. The hydrophobic tails which is non polar doesn’t react with water while the hydrophilic heads help in interaction with water.
This helps in the movement of particles in and out of the cells and stratification of the cell membrane.
