WebMolecular structure of triglycerides (fats) Triglycerides, or fats, are formed from the combination of glycerol and three fatty acid molecules. Triglycerides are formed through dehydration reactions. Another word for triglyceride is triacylglycerol. Fats can be solid (such as coconut oil) or liquid (such as vegetable oil) at room temperature.
