Arcadia Support Portal :: Please explain the D3 cycle?

Please explain the D3 cycle?

A. The following except is taken from the forthcoming book about reptiles and the undergrowth from Arcadia books.

This amazing process begins when a cholesterol called pro vitamin D(7DHC) is produced in the skin of an animal. This is a natural process in both humans and reptiles. When this cholesterol is exposed to natural light including light in the UVB wavelength (290-315nm) this cholesterol is turned in the skin membrane into pre vitamin D. This newly manufactured pre vitamin D is then converted in the skin membrane and only after exposure to warmth into vitamin D3. It is essential to have this heating up period alongside UV radiation. Vitamin D3 is then sent out into the blood plasma from this skin membrane and is bound with a vitamin D binding protein. This is then carried to the liver where this part of this vitamin is converted to a hormone called calcediol (25-hydroxy vitamin D3). Calcediol is then carried in the blood all around the body and into the kidneys where some of this hormone is turned into another hormone called calcetriol. This compound then plays an essential role in calcium metabolism and controls the levels of calcium in the blood.

Calcetriol also plays a huge role in the immune system, and the cardiovascular system and has been shown to lower the risk of cancers in the body and skin. So we can see that exposure to natural sunlight is only the start of this amazing ability in reptiles and humans alike to turn sunlight into life saving vitamins. This D3 cycle is dependent on the completion of the D3 cycle. If a part of the cycle is missed out then the cycle cannot be completed properly and the changes and reactions cannot complete properly. This would result in an under provision of essential vitamins and hormones and if supplementation were not used a calcium crash could happen. “ JCS, 2011 Arcadia reptile all rights reserved”.

    Hmm it looks like your website ate my first commnet (it was extremely long) so I guess I'll just sum it up what I wrote and say, I'm thoroughly enjoying your blog. I too am an aspiring blog blogger but I'm still new to everything. Do you have any tips for beginner blog writers? I'd certainly appreciate it.
