clear colourless to faint yellow oil
Использование
Squalene is a natural triterpene that plays an important role in the synthesis of cholesterol, steroid hormones, and vitamin D in the human body. Squalene is commonly used as a biochemical precursor i
n the preparation of steroids. Squalene is also a natural moisturizer with low acute toxicity and is not significant human skin irritants or sensitizers.
Определение
ChEBI: A triterpene consisting of 2,6,10,15,19,23-hexamethyltetracosane having six double bonds at the 2-, 6-, 10-, 14-, 18- and 22-positions with (all-E)-configuration.
Методы производства
Squalene is extracted from shark liver or synthesized from hexaphenyl-1,4-butanediyldiphosphonium dibromide and 6,10-dimethyl-5,9-undecadien-2-one (geranylacetone, industrial intermediate in the vitamin E synthesis).
