Hydrophilic (water-loving) or could be called water, it mean attracting water molecules as close as possible, the phospholipid is made up of a head that is polar, and a tail that is non polar or in another words called “hydrophobic” , this means that the head of the phospholipid is attracted to water molecules ( this helps you understand the structure of cell membrane formation). Steriod, a class of lipids, some hormones like cholesterol are made up of steroids. They maintain fluidity of cell membrane. Example: oestrogens
The correct answer is: Genome-wide association studies.
