Abstract
Two previously uncharacterized radioactive estrogen conjugates, 17beta-estradiol-17-beta-D-glucuronide (3-hydroxyestra-1,3,5(10)-trien-17beta-D-glucopyranosiduronate) and 17alpha-estradiol-17beta-D-glucuronide (3-hydroxyestra-1,3,5(10)-trien-17alpha-yl-beta-D-glucopyranosiduronate), have been identified in small but significant amounts in avian urine and in a ratio of approximately 2:1 after intramuscular injection of [4-14C]estrone.
摘要
两种先前未被表征的放射性雌激素共轭物，17β-雌二醇-17-β-D-葡萄糖醛酸苷（3-羟基雌甾-1,3,5(10)-三烯-17β-D-葡萄糖吡喃糖醛酸苷）和17α-雌二醇-17β-D-葡萄糖醛酸苷（3-羟基雌甾-1,3,5(10)-三烯-17α-基-β-D-葡萄糖吡喃糖醛酸苷），已在鸟类尿液中被鉴定出，含量虽少但具有显著意义，且在肌肉注射[4-¹⁴C]雌酮后，其比例约为2:1。
