Figure 1From: Identification and structural elucidation of ozonation transformation products of estroneMolecular structure of estrone (E1) showing the standard C atom numbering and two possible structures for each of the identified OTPs. OTP-276B was not observed, while OTP-318B was 10 times less abundant than OTP-318A. Wavy bonds indicate that the exact stereochemistry is unknown.Back to article page
