Squalane is a lipid found in some fish oils (especially shark liver oil) and some vegetable oils. It has anticancer and antioxidant properties and is used as a skin moisturizer and emollient.

Batilol (Stearyl monoglyceride), isolated from shark liver oil, is also present in yellow bone marrow of animals and has been described as an inflammatory agent.

Squalene (AddaVax) is a natural organic compound originally obtained for commercial purposes primarily from shark liver oil, though there are botanical sources as well, including rice bran, wheat germ, and olives. All higher organisms produce squalene, including humans. Squalene is an intermediate product in the synthesis of cholesterol and shows several pharmacological properties such as hypolipidemic, hepatoprotective, cardioprotective, antioxidant, and antitoxicant activity.

Squalamine lactate, an aminosterol compound discovered in the tissues of the dogfish shark, exhibits antimicrobial activity.

Pristane (2,6,10,14-tetramethylpentadecane) is a natural product from shark liver oil and a non-antigenic adjuvant.
