Squalene is an organic compound.It is a triterpene with the formula C 30 H 50.It is a colourless oil, although impure samples appear yellow. It was originally obtained from shark liver oil (hence its name, as Squalus is a genus of sharks).
Squalene was traditionally sourced from the livers of sharks, with approximately 3000 required to produce one ton of squalane. [5] Due to environmental concerns, other sources such as olive oil, rice and sugar cane have been commercialized, and as of 2014 have been supplying about 40% of the industry total.
A principal component of many shark oils is squalene, a triterpenoid (C 30 H 50), ranging up to 90% of the oil, depending on the species. In Centrophorus species squalene may account for 15% of the total body weight. Pristane, another terpenoid (C 19 H 40), is often a minor component, ranging up to nearly 8% of the oil. [12]

Squalene is biosynthesized through the head-to-head condensation of two farnesyl pyrophosphate units. This coupling converts a pair of C15 components into a C30 product. Squalene serves as precursor for the formation of many triterpenoids, including bacterial hopanoids and eukaryotic sterols.
