Chromatographic separation of vitamin D3 sulfate and vitamin D3

Steroids, 1978
This paper describes a simple chromatographic technique on Sephadex LH20 for the separation of vitamin D3 sulfate from free vitamin D3 and its metabolites. This technique has been used in the study of vitamin D3 sulfate metabolism in rats. Seven hours after injection of vitamin D3 sulfate (35S or 35S and 3H) only the peak of vitamin D sulfoconjugate ...

[Vitamin D3].

Nihon rinsho. Japanese journal of clinical medicine, 1993
With the application of biochemical technique came the discovery that vitamin D is metabolized sequentially to 25-hydroxyvitamin D in liver and then to 1.25-dihydroxyvitamin D (1.25D), the hormonal form of vitamin D, in kidney. The latter process is strictly controlled with the demand of calcium and phosphorus.

Vitamin d3 and brain development

Neuroscience, 2003
Evidence for the presence of the vitamin D receptor in brain implies this vitamin may have some function in this organ. This study investigates whether vitamin D(3) acts during brain development. We demonstrate that rats born to vitamin D(3)-deficient mothers had profound alterations in the brain at birth.

[Vitamin D2 or vitamin D3?].

La Revue de medecine interne, 2008
Nearly one billion people around the world are deficient in vitamin D and need to be supplemented. Vitamin D is available in medicines and fortified foods. It is available in two forms: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).The pharmacopeiae consider these steroid hormones as equivalent and interchangeable.

The Vitamin D3-Hormon

2016
Most tissue types carry receptors for the vitamin D3 hormone and are therefore receptive to its myriad control signals. It exercises a regulatory function over the activity of at least 200 genes. One important responsibility of this hormone lies in bone metabolism (Chapter 75) and in optimizing the body’s neuromuscular coordination.
