Vitamins

<p>Stability Light Sensitive, Temperature Sensitive<br>Applications The vitamin that mediates intestinal calcium absorbtion, bone calcium metabolism and probably, muscle activity. Occurs in and is isolated from fish liver oils. Vitamin D acts through a receptor that is a member of the ligand-dependent transcription factor superfamily. Modulates the proliferation and differentiation of both normal and cancer cells. Has antiproliferative and antimetastatic effects on breast, colon, and prostate cancer cells. Activated vitamin D receptors in intestine and bone maintain calcium absorbance and homeostasis.<br> Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package<br>References Haussler, R., et al.: J.

<p>Applications The main metabolite of Vitamin D3. It has potent biological activity. Vitamin D3-sulfate had &lt;5% of the activity of vitamin D3 to mobilize Ca from bone and .apprx.1% of the ability of Vitamin D3 to stimulate Ca transport, elevate serum P, or support bone calcification.<br>References Bell, P.A., et al.: Biochem.
