Description générale

Desmosterol lacks a double bond between C24 and C25 compared to cholesterol. It is present in the membrane of spermatozoa and astrocytes and is the major brain sterol.

Application

Desmosterol has been used as a sterol to test its interaction with human protein Mincle and as an internal standard in ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). It may be used as in the preparation of lipid monolayers.

Actions biochimiques/physiologiques

Desmosterol is a precursor of cholesterol in the Bloch pathway and the enzyme 24-dehydrocholesterol reductase catalyzes this step. Desmosterol accumulates during impairment of 24-dehydrocholesterol reductase enzyme thereby leading to desmosterolosis. Desmosterol is a liver X receptor (LXR) agonist . It is a potential therapeutic target for treating the neurodegenerative disorder. Desmosterol regulates inflammatory signaling in macrophages.

Ram sperm are particularly sensitive to freeze-thawing mainly due to their lipid composition, limiting their use in artificial insemination programs. We evaluated the extent of cholesterol and desmosterol incorporation into ram sperm through incubation with increasing concentrations of methyl-β-cyclodextrin (MβCD)-sterol

Cholesterol and cholesterol-derived oxysterols are critical for embryonic development, synapse formation and function, and myelination, among other biological functions. Indeed, alterations in levels of cholesterol, sterol precursors, and oxysterols result in a variety of developmental disorders, emphasizing the importance of

The formation and properties of liquid-ordered (Lo) lipid domains (rafts) in the plasma membrane are still poorly understood. This limits our ability to manipulate ordered lipid domain-dependent biological functions. Giant plasma membrane vesicles (GPMVs) undergo large-scale phase separations into coexisting
