What property makes phospholipids ideal building blocks for cell membranes?

The phospholipids are amphipathic, which means they contain polar heads and non-polar tails (it is required to form phospholipid bilayers).

In conclusion, the phospholipids are amphipathic, which means they contain polar heads and non-polar tails (it is required to form phospholipid bilayers).

They have hydrophilic heads and hydrophobic tails

Explanation:

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.
