The simplest lipids constructed from fatty acids are the triglycerides, also referred to as
triglycerides, fats, or neutral fats. triglycerides are composed of three fatty acids, each in ester
linkage with a single glycerol.

Those containing the same kind of fatty acid in all three positions are called simple triglycerides and are named after the fatty acid they contain. Simple triglycerides of 16:0, 18:0, and 18:1, for example, are tripalmitin, tristearin, and triolein,
respectively. Most naturally occurring triglycerides are mixed; they contain two or three different fatty acids. To name these compounds unambiguously, the name and position of each fatty acid must be specified.
