Question
The phosphoglycerides is ____ at the fatty acid end.

The phosphoglycerides is polar at the phosphate end and nonpolar at the fatty acid end.
Note: When forming bilayer membranes, the polar heads of phospholipids are able to face toward the watery environment within and outside the cell, while the tails create a nonpolar inner layer within the membrane, creating a barrier to polar molecules that allows the regulation of their passage in and out of the cell.
