What are fats composed of?

Fats, also known as lipids, are primarily composed of fatty acids and glycerol. This structure is essential for the role that fats play in the body. Fatty acids are long hydrocarbon chains that can be saturated or unsaturated, while glycerol is a three-carbon alcohol that serves as the backbone for fat molecules. When three fatty acids bond with one glycerol molecule, they form a triglyceride, which is the main form of fat found in food and stored in the body.

Fats are important for various physiological functions, including energy storage, insulation, and protection of vital organs. They also play a critical role in cellular structure, as they are essential components of cell membranes. Understanding the composition of fats helps in recognizing their significance in nutrition and metabolism.
