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 ...
Assessed 8 vitamin D metabolites in participants with cystic fibrosis and controls.Total 25(OH)D was comparable between participants with cystic fibrosis and controls.Total 1α,25(OH)2D, 4β,25(OH)2D3, 25(OH)D3-3-sulfate were lower in cystic fibrosis.Clearance of 25(OH)D3did not differ...

Here we interrogated, using three separate but complementary experimental approaches, the impact of vitamin Bavailability and methotrexate exposure on Daphnia magna, which we hypothesised should have an opposite effect on One carbon metabolism (OCM). OCM is a vital biological process supporting a ...
(əˈskɔr bɪk) n. a white, crystalline, water-soluble vitamin, C6H8O6, occurring naturally in citrus fruits, green vegetables, etc., and also produced synthetically, essential for normal metabolism: used in the prevention and treatment of scurvy, and in wound-healing and tissue ...

B vitamins such as folate (B9), B6, and B12 are key in one carbon metabolism, which generates methyl donors for DNA methylation. Several studies have linked differential methylation to self-reported intakes of folate and B12, but these estimates can be imprecise, while metabolomic biomarkers can...
A reduced activity of placental metabolism will diminish fetal vitamin supply. ZEMPLEP Placenta Maternal tissues Figure 1. Diagram of the blood flow through the placenta (arrows indicate direction of blood flow). A simplified model of a concurrent exchanger is shown (3). Once the vitamin has ...
Methods of labelling calciferol in specified positions with tritium have been investigated with the purpose of selecting a stable and highly radioactive compound for metabolic studies. [3α-3H]Ergocalciferol and [24, 25, 26, 27-3H9]-, [7-3H]-, [6-3H]- and [1α-3H]-cholecalciferol have...
