Which of the following statements about phospholipids is TRUE? A Option A: Each one has two fatty acid chains and the glycerol b
Diano4ka-milaya [45]

Answer:

Each one has two fatty acid chains and the glycerol backbone is bonded to a small polar group.

Explanation:

Phospholipid is a unique form of lipid. The  bonding of the glycerol backbone to the polar phosphate group makes phospholipid to have dual solubility unlike general triglycerides.

 

The polar head is said to be hydrophillic that is <u>water loving,</u> while the two carbon chains  that  retained lipid features are hydrophobic <u>water hating.</u>

Therefore if a phopholipid is placed in water, in relation  to its functions as component of cell membrane, it forms a bi-layer in which the water loving portion hydrophilic head points into the surrounding watery medium, while the hydrophobic layer points inwards far away from the watery medium into the internal cellular  layer to form an impermeable barrier to hydrophilic (polar) substances.

This forms the basis of   the  phospholipd  bilayer  of the  cell membrane. And it  controls the permeability of the cell membrane to  influx  substances  into the cells.
