(Cholecalciferol) (25-Hydroxycholecalciferol) (1α,25-Dihydroxycholecalciferol) A CALCIOTROPIC STEROID HORMONE 20 -30 days The concentration of calcidiol in blood plasma informs of the body calciol saturation Seasonal variations are observed 25 -Hydroxylation of calcidiol is inhibited by the high concentrations of calcidiol and calcitriol
calcitriol, (1α,25-dihydroxycholecalciferol), which is the most bioactive vitamin D isoform Circulating calcidiol can also be converted to calcitriol in other cell types and tissues, including the placenta (Shin et al 2010) Inactivation of vitamin D molecules results from the CYP24A1 hydroxylase, which converts both calcidiol
produces 24R,25-dihydroxycholecalciferol It is noteworthy that, CYP24 also uses calcitriol to produce 1a,24R,25-trihydroxycholecalciferol, the first product in the C-24 oxidation pathway responsible for degradation of calcitriol Comparatively little is known in teleosts concerning ‘vitamin D 3 physiology’ Indeed, classical genome-mediated
