Creative Proteomics can provide a highly sensitive and fast gas chromatography-mass spectrometry (GC-MS/MS) method for the determination of squalene content, which can meet the rapid and high-throughput detection of squalene in multiple sample types. It can speed up the research and application of researchers in exploring natural squalene resources other than sharks and chemical synthesis.

Overview

Squalene is an isoprenoid compound composed of 6 non-conjugated double bonds and has strong antioxidant activity. Therefore, squalene is mainly used as a functional food additive in food. Squalene not only exists in animals and plants, but is also distributed in microorganisms. Squalene has an oxygen-carrying function similar to red blood cells. It combines with oxygen in the body to generate activated oxygenated squalene, which is transported to the terminal cells of the body through the blood circulation and releases oxygen to promote the biological oxidation-reduction reaction in the body's metabolism. It also has anti-cancer and anti-cancer effects. Squalene has the effects of anti-oxidation and resistance to ultraviolet rays, and is widely used as an emollient. In order to enhance the therapeutic effect of drugs, squalene is widely used as a drug slow-release agent. The gas chromatography-mass spectrometry method has the advantages of high efficiency and rapidity, simple operation, low pollution and high detection sensitivity, which can meet the rapid and high-throughput detection of squalene in multiple sample types.
