Abstract
An assay is described based on a high pressure liquid chromatography system for measurement of vitamin D3 and 25-hydroxyvitamin D3 concentration in adipose tissue and muscle. The sensitivity of the assay is less than 1 ng/g of tissue. Neither vitamin D3 nor 25-hydroxyvitamin D3 were found in tissues of vitamin D-deficient rats using this method. 25-Hydroxyvitamin D3 could not be detected in adipose tissue and very little was found in muscle of normal rats. The mean vitamin D3 concentrations in 15 samples of human perirenal adipose tissue was 45.3 ng/g +/- 22.2 (SD) and in 6 samples of axillary tissue 115.6 ng/g +/- 52.4 (SD). Human adipose tissue contains a substantial amount of vitamin D3 and its contribution to the maintenance of vitamin D status is discussed.Entities:
