7-Desidrocolesterolo

Descrizione:

7-Desidrocolesterolo, con il numero CAS 434-16-2, è uno sterolo e un precursore nella biosintesi del colesterolo. È caratterizzato dalla sua formula molecolare C27H44O e presenta una struttura che include un nucleo steroideo con un doppio legame nella posizione del settimo carbonio. Questo composto è un solido cristallino incolore, insolubile in acqua ma solubile in solventi organici. 7-Desidrocolesterolo svolge un ruolo cruciale nel corpo umano, in particolare nella pelle, dove può essere convertito in vitamina D3 all'esposizione alla luce ultravioletta. Questa conversione è vitale per il metabolismo del calcio e la salute delle ossa. Inoltre, 7-Desidrocolesterolo è utilizzato in varie applicazioni biochimiche e farmaceutiche, inclusa la ricerca sul metabolismo del colesterolo e la sintesi di ormoni steroidei. Le sue proprietà uniche e la sua importanza biologica lo rendono un composto importante sia in biochimica che in medicina.

7-Dehydrocholesterol is a cholesterol precursor that is synthesized in the skin and liver. It is also found in other tissues, including the brain, where it is converted to cholesterol. 7-Dehydrocholesterol can be used as an indicator of sterol metabolism because its concentration reflects the rate of cholesterol production by the body. The kinetics of 7-dehydrocholesterol are similar to those of cholesterol, and it has been used as a marker for measuring cholesterol synthesis rates in humans. Skin cells contain 7-dehydrocholesterol, which may be important for skin cancer prevention. 7-Dehydrocholesterol has also been shown to be effective in reducing autoimmune diseases such as lupus erythematodes and bowel diseases such as Crohn's disease, although further research is needed.

7-Dehydrocholesterol is a sterol found in cells. It is the immediate precursor of cholesterol, which is synthesized from 7-dehydrocholesterol by the enzyme 7-dehydrocholesterol reductase. This compound has been shown to be an important regulator of mitochondrial membrane potential and ATP synthesis in neuro2a cells. Furthermore, 7-dehydrocholesterol has been shown to have therapeutic effects on metabolic disorders, skin cancer, and polymerase chain reactions. It also has receptor activity and enzyme activities that are not yet well understood. The untreated group had higher levels of 7-dehydrocholesterol than the treated group.
