Composition of Fat Droplets
What is the substance that is stored in an adipocyte’s fat droplets?
It is usually a complex mixture of different types of fat molecules and other related molecules. Depending on its composition, a fat molecule can be solid (commonly referred to as “fat”) or liquid (referred to as “oil”) at room temperature.
