The phospholipid present in the cell membrane has
Options
- Ahydrophilic head and hydrophobic tails
- Bhydrophobic head and hydrophilic tails
- Chydrophilic head and hydrophilic tails
- Dhydrophobic head and hydrophobic tails
Correct answer
A. hydrophilic head and hydrophobic tails
Step-by-step solution
Phospholipids are lipid molecules made up of two fatty acids, glycerol and a phosphate group. They are components of the cell membrane and allow passage of selected substances in and out of the cell. The structure of these lipids is bilayered with a hydrophilic head (water-loving) and a hydrophobic tail (water-hating). Due to this property, they are also called amphipathic.
