Alkylresorcinols [ARs] have been proposed for use as biomarkers of whole-grain intake. The aim here was to examine the responsiveness of AR metabolites to rye intake. Sixty women were divided into three groups according to their rye consumption. We observed significant differences between groups in plasma 3-[3,5-dihydroxyphenyl]-1-propanoic acid [DHPPA] and(More)
BACKGROUND Estrone and its sulfated esters are the most abundant estrogens in blood in men and in women after the menopause. However, previous studies on the esterification of estrone with fatty acids have yielded conflicting results, some studies reporting high nanomolar concentrations of estrone fatty acyl esters in plasma. METHODS We developed an(More)
Dehydroepiandrosterone-fatty acyl esters (DHEA-FAE) are naturally occurring water-insoluble metabolites of DHEA, which are transported in plasma exclusively by lipoproteins. To find out whether DHEA, like estradiol, might be stored in adipose tissue in FAE form, we set up a mass spectrometric method to quantify DHEA-FAE and free DHEA in human adipose tissue(More)
