Triglyceride vs. Triacylglycerol: Know the Difference
By Shumaila Saeed || Updated on December 26, 2023
Triglycerides and triacylglycerols are essentially the same, with triglycerides being the common name and triacylglycerols the chemical term for fats stored in the body and found in foods.
Key Differences
Triglycerides are a type of fat found in the blood, commonly known in the context of health and nutrition. Triacylglycerol, the more technical term, refers to the same chemical compound, emphasizing its molecular structure.

In medical and dietary discussions, the term triglyceride is often used, especially in reference to blood lipid levels or dietary fat. Triacylglycerol, meanwhile, is used more in biochemical and scientific texts, detailing the structure of three fatty acids linked to a glycerol molecule.

When discussing health risks like heart disease, doctors refer to high or low triglyceride levels. In scientific research, however, triacylglycerols are discussed in terms of their chemical behavior and role in metabolism.

The term triglyceride is more recognized in everyday language and is often seen on nutrition labels and health reports. Triacylglycerol is typically reserved for academic, scientific, and professional discussions regarding fat chemistry.
