since intestinal calcium-binding protein ( cabp ) can be regarded as an expression of the hormone-like action of 1,25-dihydroxyvitamin d3 ( 1,25- ( oh ) 2d3 ) on the duodenal enterocyte we have investigated the potential biological activity of 25r and 25s,26- ( oh ) 2d3 ( two recently synthesized epimers of vitamin d3 metabolite ) to promote intestinal cabp production as compared to bone calcium mobilization in vitamin d and calcium-deficient rats .
