23, 25, 26-trihydroxycholecalciferol. A 25-hydroxycholecalciferol-26,23-lactone precursor.
(23S)-23,25-Dihydroxycholecalciferol was converted into at least five metabolites in kidney homogenates prepared from 1,25-dihydroxycholecalciferol-treated chickens. One of these has been positively identified as 23,25,26-trihydroxycholecalciferol by u.v.-absorbance analysis, mass spectrometry and chemical formation of derivatives. 23,25,26-Trihydroxycholecaciferol produces 25-hydroxycholecalci...
متن کاملCompetitive protein-binding assay for 25-hydroxycholecalciferol.
1. A competitive protein-binding assay for plasma 25-hydroxycholecalciferol was developed, using Sephadex LH-20 columns for the isolation of the sterol and a partially purified protein from rat serum as the binding protein. 2. The mean plasma 25-hydroxycholecalciferol in eighteen male and female normal volunteers was 38 5 SD 14 pmol/ml (1 5.2 & 5.6 nglml). 3. Levels of 25-hydroxycholecalciferol...
متن کامل25-hydroxycholecalciferol stimulation of muscle metabolism.
Intact diaphragms from vitamin D-deficient rats were incubated in vitro with [3H]leucine. Oral administration of 10 mug (400 U) of cholecalciferol 7 h before incubation increased leucine incorporation into diaphragm muscle protein by 136% (P less than 0.001) of the preparation from untreated animals. Nephrectomy did not obliterate this response. ATP content of the diaphragm muscle was also enha...
متن کاملReduction of Saliva and Serum 25-Hydroxycholecalciferol in Multiple Sclerosis
Methods: The prevalence of multiple sclerosis (MS) is high in patients suffering from 25-hydroxyvitamin D3 [25(OH)D] deficiency. The aim of this study was to investigate the possible association of saliva and serum 25(OH)D concentrations with MS in women.Methods: Serum and saliva 25(OH)D levels of 30 MS women and 30 matched healthy controls in this case-control study were measured by ELIS...
متن کاملControl of 25-hydroxycholecalciferol metabolism by parathyroid glands.
Thyroparathyroidectomy of rats on a diet low in calcium reduces production of 1,25-dihydroxycholecalciferol from 25-hydroxycholecalciferol to negligible levels within 40 hr, and increases production of another metabolite, called Va. Parathyroid extract, at a dose of 20 units per day, prevents these changes. When 40 units per day of parathyroid extract is given 48 hr after thyroparathyroidectomy...
