Estriol 3-glucuronide, or oestriol 3-glucuronide, also known as estriol 3-β-D-glucosiduronic acid, is a natural, steroidal estrogen and a glucuronic acid (β-D-glucopyranuronic acid) conjugate of estriol.[1] It is found in the urine of women as a reversibly formed metabolite of estriol.[2][3] The positional isomer of estriol 3-glucuronide, estriol 16α-glucuronide, also occurs as an endogenous metabolite of estriol, but to a much greater extent in comparison.[2][3]
