Ascorbic Acid 89-104 steroid sulfatase Homo sapiens 118-121 11870235-1 2002 The aim of this study was to characterize the mechanism of the chemical interaction between L-ascorbic acid (ASC) and tetrahydrobiopterin (BH(4)) in vitro and to examine its effect on the activity of endothelial nitric oxide synthase (eNOS) in first trimester human placentae. Ascorbic Acid 92-107 steroid sulfatase Homo sapiens 109-112 11870235-9 2002 Moreover, we demonstrated that concentrations of ASC present in the placenta as a common vitamin C supply are sufficient to protect cellular free BH(4) and may contribute to the stimulation of placental eNOS activity.
