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]
The toxic effects of UV from natural sunlight and therapeutic artificial lamps are a major concern for human health. Skin surface lipids, including unsaturated lipids such as squalene , sebaleic acid, linoleic acid , and cholesterol can be a subject of oxidation by singlet oxygen and ozone as well as free radicals.
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.
Sebum is secreted by the sebaceous gland in humans. It is primarily composed of triglycerides (≈41%), wax esters (≈26%), squalene (≈12%), and free fatty acids (≈16%). [7] [14] The composition of sebum varies across species. [14] Wax esters and squalene are unique to sebum and not produced as final products anywhere else in the body. [5]
Although many people have a fear of mushroom poisoning by "toadstools", only a small number of the many macroscopic fruiting bodies commonly known as mushrooms and toadstools have proven fatal to humans. This list is not exhaustive and does not contain many fungi that, although not deadly, are still harmful.
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 ...
Seed oils, including peanut oil and sunflower oil, have been in the news a lot recently. Dietitians explain if seed oils are healthy, and health risks of them.
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 ...
