Collection: Vitamins [Bone Metabolism Research]

Vitamins [Bone Metabolism Research] — gathers fat-soluble vitamins from the D and K groups together with their sterol precursors, such as cholecalciferol, ergocalciferol, ergosterol, and menaquinone-4, which are commonly used as reference compounds in studies of mineral metabolism pathways and bone matrix in research laboratories.

Vitamins in this category are used by biochemistry and bone pharmacology researchers as test materials in vitro and in vivo in experimental models to study calcium regulation, matrix mineralization, and the expression of bone-related proteins such as osteocalcin. Cholecalciferol and calciferol are commonly used as reference compounds in vitamin D receptor assays, while menaquinone-4 is used in research on vitamin K-dependent protein carboxylation, and ergosterol serves as a starting material for the synthesis of vitamin D analogs.

Examples of products in this collection: TCI C0314 67-97-0 Cholecalciferol, TCI C0005 50-14-6 Calciferol, TCI M2398 863-61-6 Menaquinone-4, TCI E0018 57-87-4 Ergosterol.

Pay attention to the stereochemical form and purity of the compounds, especially for cholecalciferol and ergosterol, which are sensitive to light and oxidation, and make sure the packaging and storage conditions are appropriate to maintain vitamin stability. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on the page of each item.
