compound introduction
25-羟基维生素D3（骨化二醇）是一种在肝脏中通过维生素D3（胆钙化醇）的羟基化而生成的激素原。它是合成骨化三醇或1,25-二羟维生素D3或[1,25(OH)2D3]的前体。它可作为生物标志物用于测定体内维生素D的状态。25-羟基维生素D3（6,19,19-d3）是一种氘化的25-羟基维生素D3，其中C-6和C-19位的质子被氘所取代。 应用 25-羟基维生素D3（6,19,19-d3）可用作分析标准品。 25-hydroxyvitamin D3(calcifediol) is a prohormone produced via hydroxylation of vitamin D3(cholecalciferol) in the liver. It is a precursor for the synthesis of calcitriol or 1,25-dihydroxyvitamin D3or [1,25(OH)2D3]. It is used as a biomarker to determine the status of vitamin D in the body.25-Hydroxyvitamin D3(6,19,19-d3) is a deuterated 25-hydroxyvitamin D3wherein C-6 and C-19 protons are replaced by deuterium.25-Hydroxyvitamin D3(6,19,19-d3) can be used as an analytical standard.
