Cephalins Explained:

The most common type of lipid group is triglycerides, and phosphoglycerides are very similar to triglycerides, with the exception of one of the three fatty-acids being replaced with a phosphoester group.

Cephalins contains two non-polar, hydrophobic tails and a polar head. It’s important to keep these factors in mind because these characteristics determine function within a cell.
