- Source of Squalene:
- Squalene ($C_{30}H_{50}$) is a natural acyclic triterpene unsaturated hydrocarbon.
- It is present in extraordinary concentrations (up to $60-80\%$ of liver oil) in the enlarged, lipid-rich livers of deep-sea sharks (family Squalidae and Centrophoridae, e.g., Centrophorus squamosus, Squalus acanthias).
- In deep-sea sharks, the low-density squalene provides static hydrodynamic buoyancy in lieu of a swim bladder. Squalene is industrially harvested for cosmetics, skin therapeutics, and pharmaceutical adjuvant formulations.
- Correct Option: Option 1 (Liver of sharks).
