Duchow, Elizabeth G.; Sibilska-Kaminski, Izabela K.; Plum, Lori A.; DeLuca, Hector F. published the artcile< Vitamin D esters are the major form of vitamin D produced by UV irradiation in mice>, Reference of 434-16-2, the main research area is vitamin D ester UV irradiation; 7-Dehydrocholesterol; Skin; Ultraviolet light B; Vitamin D; Vitamin D esters; Vitamin D-binding protein.

The primary source of vitamin D3 for humans is that produced in skin by UV irradiation UV B (UVB, 280-310 nm) light causes the isomerization of 7-dehydrocholesterol (7-DHC) to pre-vitamin D3 that is thermally isomerized to vitamin D3. In addition to free vitamin D3, it has been previously reported that esterified vitamin D3 is also found in the skin of rats irradiated with UVB. We found that a large fraction of the vitamin D3 precursor, 7-dehydrocholesterol is in the esterified form. Following UVB irradiation, vitamin D3 esters represent the majority of tissue vitamin D3, comprising approx. 80% in mice. Examination of vitamin D3 ester transport from skin in DBP-/- mice demonstrated that skin vitamin D3 ester content decreased only in the presence of DBP. No significant binding of vitamin D3 esters by serum was observed and no vitamin D3 esters were detectable in mouse serum after UVB treatment, indicating that the esters are hydrolyzed prior to transport into the circulation. The significance of vitamin D3 esters and their hydrolysis is the subject of current investigation.
