  • The major polar metabolite of cholecalciferol (vitamin D3) present in chick intestinal mucosa has been chemically characterized by mass spectrometric analysis to have a molecular formula of C27H4403 and a structure of 1,25-dihydroxycholecalciferol. This compound, which is produced in the kidney from 25-hydroxycholecalciferol, has been previously shown to be from 4 to 13 times as active as cholecalciferol in stimulating intestinal calcium transport. 1,25-Dihydroxycholecalciferol (previously… CONTINUE READING
