Description

25-Hydroxyvitamin D 2: 9,10-Secoergosta-5,7,10(19),22-tetraene-3,25-diol. Biologically active metabolite of vitamin D2 which is more active in curing rickets than its parent. The compound is believed to attach to the same receptor as vitamin D2 and 25-hydroxyvitamin D3. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]
