what is the active form of vit d?
calcitriol
vitamin d from the diet, or from skin synthesis, is biologically inactive. a protein enzyme must hydroxylate it to convert it to the active form. this is done in the liver and in the kidneys. as vitamin d can be synthesized in adequate amounts by most mammals exposed to sufficient sunlight, it is not an essential dietary factor, and so not technically a vitamin. instead it could be considered a hormone, with activation of the vitamin d pro-hormone resulting in the active form, calcitriol, which then produces effects via a nuclear receptor in multiple locations.

fergie first met his future mentor and friend tony de vit in 1995, when he was 15. de vit was djing at the kilwaughter house nightclub and fergie took a night off from his own dj residency (at the airport 2000 nightclub) to see him play. fergie managed to meet him in person and persuaded him to let him in the dj booth during his set. they kept in touch (fergie would call him up to 3 times a day) and from then on de vit stayed at fergie's parents' house whenever he performed in northern ireland. de vit invited him to his house in birmingham, england for a week's holiday and to experience the country's club scene. during the holiday, the ira ceasefire that was in place at the time back in northern ireland ended and fergie remained in england with de vit. fergie accompanied de vit at his dj gigs around the uk which at the time was usually around 7 or 8 gigs a week. de vit would ask fergie to record a dj mix cd for these car journeys. if he ever heard fergie manipulate the vinyl with his hand in the recording (a mixing technique he had advised him not to use) he would eject the cd and throw it out of the car window. de vit would often ask the club promoter if fergie could play a short dj set after his, with a reduction in his own set duration if required. it was around this time de vit first took fergie to trade, a weekly party held on sunday morning at the turnmills nightclub in london, where de vit had a dj residency. fergie was still only 16.
