Answers. Best Answer: A triglyceride (triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids.

In triglycerides, the hydroxyl groups of the glycerol join the carboxyl groups of the fatty acid to form ester bonds[ see the site for more. Source(s): http://en.wikipedia.org/wiki/Triglycerid...
