Lipids

Subject: Chemistry

Book: General Chemistry

Lipids are hydrophobic or amphiphilic molecules, including fats, oils, phospholipids, and steroids. They store energy, form cell membranes (phospholipid bilayers), and function as signaling molecules (hormones). Their insolubility in water arises from long hydrocarbon chains or fused rings. Lipids are vital in biology for insulation, organ protection, and cell structure, making their study essential in health and nutrition.
