lipids

Lipids are a diverse group of molecules that include fats, oils, waxes, and certain vitamins. They are primarily made of carbon, hydrogen, and oxygen, and serve various essential functions in the body. Lipids store energy efficiently, provide insulation to help regulate body temperature, and form the building blocks of cell membranes, which protect and organize cells. Additionally, some lipids act as signaling molecules, involved in communication within the body. They are hydrophobic, meaning they don’t dissolve well in water, which is why fats are stored in specialized tissues and transported in the body with the help of proteins.
