Concept explainers
Interpretation:
The difference in the cell membrane with different phospholipids needs to be explained.
Concept Introduction:
Lipids are
Phospholipid is type of lipid that contains a phosphorus atom. They are mainly found in cell membrane of plants and animals. They are also called as phosphoacylglycerol as two fatty acids with phosphate group and alcoholic group are bonded to the glycerol molecule through ester linkage.
