It is suggested that drugs may impair the normal function of vitamin B 6 by reducing tissue PLP levels, either through chemical reaction between drug and PLP or by inhibition of PLP synthesis. Drugs may also inhibit PLP-dependent enzymes without affecting systemic PLP levels....

In the second part, the structure-function relationship of vitamin D was analyzed based on the ligand struc-ture, in particular by using systematic conformational analysis as a tool. On the basis of the conformational analysis of the vitamin D side chain and studies using conformationally ...
Objective : The purpose of this study is to identify the main food sources of vitamin D in elderly subjects and to analyse whether contributing food sources differ by sex, age, vitamin D status, body mass index (BMI), or household income. In addition, we analysed the factors that influence...

1alpha-Hydroxy [6-3H]vitamin D3 has been synthesized with a specific activity of 4 Ci/mmol, and its metabolism in rats has been studied. It is rapidly converted to 1alpha,25-dihydroxy [6-3H]vitamin D3 in vivo. Following an intravenous or oral dose, a maximal concentration of 1alpha,...
Vitamin D is a fat-soluble vitamin obtainable from the diet, as well as a seco-steroidal prohormone produced in the skin by ultraviolet B (UVB, 290–320 nm) from sunlight. Vitamin D, as a precursor of a potent steroid hormone, undergoes two-step metabolism in the liver and kidney to...
Vitamin D, either derived from the diet or skin production, has become an increasingly important molecule in human function because of the extended longevity of human populations in many nations. The actual vitamin D requirements of elderly individuals remain difficult to determine because environmental...
