What is the physiological importance of fats?

Fats play several critical physiological roles in the body, including serving as a major source of energy, providing insulation and protection for vital organs, and aiding in the absorption of fat-soluble vitamins (A, D, E, and K). They also contribute to cell membrane structure and function, helping to maintain cellular integrity and fluidity. Additionally, certain fats, such as omega-3 and omega-6 fatty acids, are essential for various bodily functions, including hormone production and inflammation regulation.
