Lipids

Lipids are a diverse group of organic molecules that are key to numerous biological functions in living organisms. Comprising fats, oils, waxes, phospholipids, and steroids, they are primarily characterized by their hydrophobic nature, making them insoluble in water. Lipids play essential roles in cellular structure, forming the fundamental components of cell membranes, and serving as energy storage molecules that provide insulation and protection. Furthermore, they are involved in signaling pathways, facilitating communication between cells, and acting as precursors for important hormones, contributing significantly to overall metabolic processes and maintaining cellular homeostasis.
