Vaccination, squalene and anti-squalene antibodies: Facts or fiction?
European Journal of Internal Medicine, 2010Squalene, a hydrocarbon obtained for commercial purposes primarily from shark liver oil and other botanic sources, is increasingly used as an immunologic adjuvant in several vaccines, including seasonal and the novel influenza A (H1N1) 2009 pandemic flu vaccines.

An NMR and molecular mechanics study of squalene and squalene derivatives
Chemistry and Physics of Lipids, 1994Various squalene derivatives, including squalene, squalene 2,3-epoxide (monoepoxide, SQME), squalene 2,3;22,23-diepoxide (SQDE), 2-aza-2,3-dihydrosqualene (SQN) and 2-aza-2,3-dihydrosqualene N-oxide (SQNO), were studied in chloroform solutions using ID high-resolution 1H spectra and 13C longitudinal relaxation studies, 2D proton NOESY and COSY and 2D ...

Squalene in Petroleum Asphaltenes
Science, 1981Squalene, 2,6,10,15,19,23-hexamethyl-2,6,10,14,18,22-tetracosahexaene, a new biological marker, has been detected in various petroleum asphaltenes and their pyrolysis products. Since squalene is the most common triterpenoid in nature and the biological precursor of the important tetra- and pentacyclic triterpane markers, its detection in asphaltene ...

Squalene synthase (SQase) catalyzes the condensation of two molecules of farnesyl diphosphate (FPP) to form presqualene diphosphate (PSPP) and the subsequent rearrangement and NADPH-dependent reduction of PSPP to squalene (SQ). These reactions are the first committed steps in cholesterol biosynthesis.

Regulation of squalene synthetase and squalene epoxidase activities insaccharomyces cerevisiae
Lipids, 1989AbstractSqualene synthetase (EC 2.5.1.21) and squalene epoxidase (EC 1.14 99.7) activities have been measured in cell‐free extracts of wild type yeast grown in aerobic and semianaerobic conditions as well as in sterol‐auxotrophic mutant strains grown aerobically.

[9] Synthesis of labeled squalene and squalene 2,3-oxide
1969Publisher Summary Squalene 2,3-oxide is an intermediate in the enzymatic cyclization of squalene to lanosterol, and, in consequence, this aspect of steroid and terpenoid biogenesis has become the center of renewed interest. This chapter describes the improved methods for the chemical synthesis of labeled squalene and squalene 2,3-oxide.

Chemists at the University of Utah, Salt Lake City, have trapped a cationic intermediate in the biosynthesis of squalene, a key precursor of cholesterol. Their insights into the remarkable enzymatic reaction may offer important leads to the design of drugs that reduce cholesterol levels by blocking squalene biosynthesis.
