(e.g., vitamin D is added to milk). Loss of vitamins may also occur when food is cooked; for instance, heat destroys vitamin A, and water-soluble vitamins may be extracted from food towaterand lost. Certain vitamins (e.g., B vitamins,vitamin K) can be synthesized by microorganisms ...
to poverty or accessibility. Research on increasing the intake of Vit C through agronomic crops has expanded for many reasons. One of the most important reasons being that Vit C is not biosynthesized by humans, and so must be consumed4. Ever since the discovery that Vit C plays major role ...
Vitamin D is an organic compound that is one of the fat-soluble vitamins. The other fat-soluble vitamins are vitamins A, E, and K. Vitamin D can be naturally synthesized in the skin of humans and other animals in the presence of sunlight. Vitamin D plays a major role in calcium metabol...
An examination of 506 regions found a close inverse correlation between cancer mortality and levels of ultraviolet B light. The likeliest mechanism for a protective effect of sunlight is vitamin D, which is synthesized by the body in the presence of ultraviolet B. The study's author, Dr Willia...
Measurements of ambient UV (295–400nm) (using a portable photometer/radiometer and detector) and synthesized vitamin D (from an in vitro model) were taken regularly at urban and control sites over 3months in Brisbane, Australia. During a typical 20min measurement, urban and control sites ...

Vitamin D3 is synthesized in the skin when its precursor, 7-dehydrocholesterol, is exposed to ultraviolet B (UVB) in sunlight. Once vitamin D3 is...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
Ileal absorption of B12 requires intrinsic factor, which is synthesized by gastricparietal cells, as well as by pancreatic ductular cells in dogs and cats. The association of Co+++ with B12 is the primary recognized action of this trace element in mammalian metabolism. Entry of propionate into ...
