                                The vast majority of fats and oils found in nature and our diets are in the form of triglycerides. These molecules share a common chemical feature that dictates their structure and properties: a specific functional group called an ester. Understanding this fundamental chemical bond is key to understanding how fats are formed, stored, and used by living organisms.
