Explain how the structure of lipids determines the polarity of the molecule

There are different types of lipid and the polarity of a lipid depends on the characteristics of the components that made up a particular lipid. For instance, triglycerides are made up of fatty acids and glycerol. The fatty acids are hydrophobic in nature, thus, the triglycerides are non polar molecules. Phospholipids on the other hand are bilayer in nature and possess two distinct regions, a head and a tail. The head region is polar and the tail region in non polar as a result of the components that are found in these regions.
