Hi SuEs. Well, the enzyme that performs the forward reaction, DHCR7, is technically capable of preforming the reverse reaction (, but not under physiological conditions where [NADPH] out numbers [NADP+] by at least 100:1 ( There is literature on the downregulation of DHCR7 in response to high levels of cholesterol, leading to increased vitamin D production (, but I also can't find anything about biological reactions that convert cholesterol back into 7DHC.
