Answer;
- phosphate group
- Ester functional group
- Alkene
- Alkane side chains.
Explanation;
Phospholipids are types of lipids that are major components of the cell membranes.
They consist both the hydrophillic (water loving) and hydrophobic (water hating) ends.
The major functional groups in a phospholipids are;
- the phosphate groups - PO4
- The Ester functional group- - COO-R
- Alkene side chain - -CH=CH-
- Alkane side chain - -CH-CH-
