Nutrition in Large Breed Puppies

Whether it is made in the skin or ingested, Vitamin D is hydroxylated in the liver at position 25 upper right of the molecule to form hydroxycholecalciferol calcifediol or 25 OH D. The conversion of calcifediol to calcitriol is catalyzed by the enzyme hydroxyvitamin D 3 1-alpha-hydroxylase , which is the product of the CYP27B1 human gene. The activity of CYP27B1 is increased by parathyroid hormone , and also by low calcium or phosphate. Following the final converting step in the kidney, calcitriol is released into the circulation.

By binding to vitamin D-binding protein, calcitriol is transported throughout the body, including to the classical target organs of intestine, kidney and bone. In addition to the kidneys, calcitriol is also synthesized by certain other cells including monocyte - macrophages in the immune system.

When synthesized by monocyte-macrophages, calcitriol acts locally as a cytokine , modulating body defenses against microbial invaders by stimulating the innate immune system. The activity of calcifediol and calcitriol can be reduced by hydroxylation at position 24 by vitamin D3 hydroxylase , forming secalciferol and calcitetrol respecively. American researchers Elmer McCollum and Marguerite Davis in [9] discovered a substance in cod liver oil which later was called "vitamin A". British doctor Edward Mellanby noticed dogs that were fed cod liver oil did not develop rickets and concluded vitamin A, or a closely associated factor, could prevent the disease.

In , Elmer McCollum tested modified cod liver oil in which the vitamin A had been destroyed. He called it vitamin D because it was the fourth vitamin to be named. In , [9] it was established that when 7-dehydrocholesterol is irradiated with light, a form of a fat-soluble vitamin is produced now known as D 3.

Alfred Fabian Hess stated: A meeting took place with J. Bernal , and Dorothy Crowfoot to discuss possible structures, which contributed to bringing a team together. X-ray crystallography demonstrated the sterol molecules were flat, not as proposed by the German team led by Windaus. In , Otto Rosenheim and Harold King published a paper putting forward structures for sterols and bile acids which found immediate acceptance.

In the s, Windaus clarified further the chemical structure of vitamin D. In , American biochemist Harry Steenbock at the University of Wisconsin demonstrated that irradiation by ultraviolet light increased the vitamin D content of foods and other organic materials. A vitamin D deficiency is a known cause of rickets. His irradiation technique was used for foodstuffs, most memorably for milk.

By the expiration of his patent in , rickets had been all but eliminated in the US. In , after studying nuclear fragments of intestinal cells, a specific binding protein for Vitamin D called the Vitamin D Receptor was identified by Mark Haussler and Tony Norman.

In the liver, vitamin D was found to be converted to calcifediol. Calcifediol is then converted by the kidneys to calcitriol, the biologically active form of vitamin D.

The vitamin D metabolites, calcifediol and calcitriol, were identified by competing teams led by Michael F. There is considerable research activity looking at effects of vitamin D and its metabolites in animal models, cell systems, gene expression studies, epidemiology and clinical therapeutics. These different types of studies can produce conflicting evidence as to the benefits of interventions with vitamin D. They suggest, for some people, reducing the risk of preventable disease requires a higher level of vitamin D than that recommended by the IOM.

Until such trials are conducted, the implications of the available evidence for public health and patient care will be debated". Some preliminary studies link low vitamin D levels with disease later in life.

Vitamin D deficiency is widespread in the European population. Apart from VDR activation, various alternative mechanisms of action are under study, such as inhibition of signal transduction by hedgehog , a hormone involved in morphogenesis.

Although much of the vitamin D produced within human skin is absorbed directly, birds and furbearing animals acquire most of their vitamin D orally, as they groom themselves Bicknell and Prescott, ; Carpenter and Zhao, Vitamin D is generated from the oily secretions of skin into fur.

Although Fraser has argued that dermal absorption of vitamin D may be more natural, what we know from animals indicates that oral consumption is equally physiological. Since vitamin D can be extracted from UV-exposed human sweat and skin secretions Bicknell and Prescott, , it is also reasonable to think that early humans obtained some of their vitamin D by mouth as well, by licking the skin.
