Ningbo Inno Pharmchem Co., Ltd. is proud to highlight the significance of 7-dehydrocholesterol, a compound identified by CAS 434-16-2, in the realms of human health and metabolic science. This compound is more than just a chemical entity; it is a cornerstone in two of the body's most vital biological processes: Vitamin D synthesis and cholesterol metabolism. Understanding the intricacies of 7-dehydrocholesterol is paramount for researchers and industries focused on health and wellness.

At its core, 7-dehydrocholesterol serves as a provitamin, specifically the precursor to Vitamin D3. This conversion is famously triggered by ultraviolet B (UVB) radiation, such as sunlight, which human skin readily absorbs. This photochemical reaction transforms 7-dehydrocholesterol into previtamin D3, which then undergoes a thermal isomerization to vitamin D3. This pathway is crucial for maintaining adequate Vitamin D levels, essential for calcium absorption, bone health, immune function, and numerous other physiological processes. For those seeking to buy 7-dehydrocholesterol for research or development, understanding this biological role is key.

Beyond its role in Vitamin D production, 7-dehydrocholesterol is also a pivotal cholesterol biosynthesis intermediate. In most tissues, it is the immediate precursor to cholesterol, being converted in the final step of the biosynthesis pathway by the enzyme 3β-hydroxysterol-Δ7-reductase (DHCR7). This function places 7-dehydrocholesterol at the heart of cellular membrane structure and function, as well as steroid hormone synthesis. When this pathway is disrupted, as in conditions like Smith-Lemli-Opitz syndrome (SLOS), the accumulation of 7-dehydrocholesterol can lead to severe developmental and health issues. Researchers studying SLOS often rely on high-quality 7-dehydrocholesterol for their investigations, making its availability and purity critical.

The chemical and biological properties of 7-dehydrocholesterol are well-documented. It is generally a solid at room temperature, with a melting point typically in the range of 148-152 °C. Its insolubility in water and its susceptibility to oxidation are important considerations for handling and storage. The demand for 7-dehydrocholesterol, especially for pharmaceutical intermediates and research applications, remains consistently high. Ningbo Inno Pharmchem Co., Ltd. is committed to supplying this essential compound, supporting advancements in both Vitamin D research and the broader field of lipid biochemistry.

In summary, the importance of 7-dehydrocholesterol cannot be overstated. Its dual function as a provitamin for Vitamin D3 and a cholesterol biosynthesis intermediate makes it an indispensable molecule. Whether for understanding skin photobiology, investigating metabolic disorders, or developing new health solutions, access to reliable 7-dehydrocholesterol is vital. Ningbo Inno Pharmchem Co., Ltd. provides this critical material, empowering scientific discovery and product development.
