Uhh...the spelling?? j/k...I have no idea. Did you try looking it up on the internet? I'll check and see what I can find out.
EDIT* Here's what I found. Looks like one comes from Sharks and the other from Olive Trees. HTH...
Squalene
From Wikipedia, the free encyclopedia
Squalene is the biochemical precursor to the whole family of
steroids. Oxidation of one of the terminal double bonds of squalene yields
2,3-squalene oxide which undergoes enzyme-catalyzed cyclization to afford
lanosterol, which is then elaborated into
cholesterol and other steroids.
Squalene is a low density compound often stored in the bodies of
cartilaginous fishes such as
sharks, which lack a
swim bladder and must therefore reduce their body density with fats and oils. Squalene, which is stored mainly in the shark's
liver, is lighter than water with a specific gravity of 0.855.
Recently it has become a trend for sharks to be hunted to process their livers for the purpose of making squalene health capsules. However, there is little clinical evidence to prove that, taken internally, squalene does anything to increase an individual's quality of life.
Squalene is used in cosmetics as a natural, oil-free moisturizer. It also makes up 12% of
sebum, a natural product expressed by human
sebaceous glands to moisturize hair follicles.
