It is a natural 30-carbon isoprenoid compound and intermediate metabolite in the synthesis of cholesterol. It is not susceptible to lipid peroxidation and provides skin protection. It is ubiquitously distributed in human tissues where it is transported in serum generally in association with very low density lipoproteins. Squalene is investigated as an adjunctive cancer therapy."}]
