A typical fat molecule is built from one glycerol bonded to:

1. A fat has two main components, glycerol and fatty acids. 2. Glycerol carries three hydroxyl groups, one on each of its three carbons. 3. A fatty acid attaches at each of those three carbons by an ester bond. 4. So a typical fat holds three fatty acid chains, which is why fats are also called triglycerides. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 3 'Biological Macromolecules', sections 3.1-3.5_
