A triglyceride is composed of which of the following?

A triglyceride is composed of one molecule of glycerol and three fatty acids, which is the defining structure of this type of lipid. Glycerol serves as a backbone to which the fatty acids are attached through ester bonds. Each fatty acid is a long hydrocarbon chain with a carboxylic acid group, contributing to the energy storage and structural properties of triglycerides in living organisms. This structure is crucial for various biological functions, including energy storage and insulation. Therefore, understanding the composition of triglycerides is essential for comprehending their role in metabolism and nutrition.
