(liver), egg yolks, plants Vitamin D synthesis Liver: cholesterol 7-dehydrocholesterol (provitamin D 3 ) Enzyme: cholesterol dehydrogenase Skin Storage of 7-dehydrocholesterol Cleavage of 7-dehydrocholesterol via irradiation with UV light cholecalciferol (in the stratum basale) Liver: hydroxylation of cholecalciferol to 25-hydroxyvitamin D (25-OH D3, calcidiol) Kidneys: 1-hydroxylase hydroxylates 25-hydroxyvitamin D 1,25-dihydroxyvitamin D Transport to target cells: vitamin D-binding protein (DBP) Storage: as 25-hydroxycholecalciferol, mainly in adipose tissue
