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). An estimated 12% of bodily squalene in humans is found in sebum. [5]
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.

Squalamine was discovered in a search for anti-microbial compounds in the tissues of primitive vertebrates. [1] The team speculated that animals with primitive immune systems, such as sharks and lampreys, might utilize antimicrobial compounds as a significant component of their immune repertoire.
Similar to azoles, allylamines disrupt the fungal cell wall synthesis through inhibition of the squalene epoxidase enzyme that converts squalene into ergosterol. Examples of allylamines antifungals comprise amorolfin, naftifine and terbinafine. The last group consists of antifungal drugs with a different mechanism of action than the other three ...
The growth of this segment is primarily due to the use of squalene in a wide range of cosmetic products including skin care and hair care. Many global cosmetic companies such as L’Oréal, Unilever and St. Petersburg are responsible for the use of squalene. Botanica has begun to transition from shark liver oil-squalene based to plant-based ...
Steroids feature a cucurbitane core, although in practice they are biosynthesised from either lanosterol (animals and fungi) or cycloartenol (plants) via the cyclization of squalene. Steroids have two principal biological functions, being either key components of cell membranes or signaling molecules that activate steroid hormone receptors.
Squalene monooxygenase (also called squalene epoxidase) is a eukaryotic enzyme that uses NADPH and diatomic oxygen to oxidize squalene to 2,3-oxidosqualene (squalene epoxide). Squalene epoxidase catalyzes the first oxygenation step in sterol biosynthesis and is thought to be one of the rate-limiting enzymes in this pathway. [ 5 ]
