Metabolite Identification
Common Name1,25-Dihydroxyvitamin D3-26,23-lactone
Description1,25-Dihydroxyvitamin D3-26,23-lactone (1,25(OH)2D3-26,23-lactone) is a vitamin D3 metabolite. The formation of 1,25(OH)2D3-26,23-lactone occurs in normocalcemic states and in situations in which 1,25(OH)2D3 has been administered. (PMID: 6324253 ). 1,25-dihydroxyvitamin D3 and (23S)-1,23,25-trihydroxyvitamin D3 are efficient precursors to 1,25(OH)2D3-26,23-lactone. 1,25(OH)2D3-26,23-lactone has an inhibitory action of bone resorption and the lactone ring plays a major part in its expression. (PMID: 6548386 , 1666030 ).
