Abstract
Evidence is accumulating that, in vivo and in vitro, both 25-OH-D3 and 1,25-(OH)2D3 undergo side-chain modification leading to side-chain cleaved metabolites lacking the 24, 25, 26, and 27 carbons. The enzymes involved are D-dependent and are located in the kidney, bone, intestine, and perhaps other sites. We speculate that the extra-renal side-chain pathway may be primarily for target organ destruction of 1,25-(OH)2D3, whereas the renal pathway may be primarily for destruction of 25-OH-D3 formed in large amounts in hypervitaminosis D.Entities:
