Lipids Don't Interact With Water

Lipids are compounds that are insoluble in water but are soluble in organic solvents such as ether and chloroform. (source )

Lipids are involved in numerous cellular functions, including cell signaling, cell growth, and cell division.

Lipids also serve as structural components of cell membranes, and can be involved in transporting nutrients and other materials into cells.

Lipids In The Form Of Triglycerides

Lipids can be divided into several categories: triglycerides, phospholipids, sphingolipids, and sterols.

Each category is composed of many different molecules.

Triglycerides are the major source of energy for cells and are also involved in a wide variety of other metabolic processes.

Triglycerides are the most common and abundant form of lipids in most animal cells.

They are also the most abundant lipids in animal fat and vegetable oil.

In human tissues, triglycerides are an important component of the body's main energy reserve, as well as the brain.

Important Lipids

Important lipids include fats and oils, fatty acids, phospholipids, and cholesterol. (source )

Fats and oils

Fats and oils are important in the diet as energy sources. Especially sources of essential fatty acids and fat-soluble vitamins, which tend to be associated with fats. (source )

Fatty acids

Fatty acids supply the energy consumed in cellular growth at certain stages of life. (source )
