Cholesterol A lipid serving as a precursor for vitamin D, bile, and hormones such as testosterone and estrogen. Phospholipids Molecules forming the main component of cell membranes, crucial for cellular structure and function. Visceral Fat Fat stored around internal organs, providing cushioning and protection from physical impact. Satiety A feeling of fullness after eating, often enhanced by the presence of fats in foods. Fat-Soluble Vitamins Nutrients such as vitamins A, D, E, and K, which require lipids for absorption and transport in the body.
