Chemical Formula Structural Representation

This image displays the complex structural formula of an organic molecule. It features a steroid backbone, characterized by its fused four-ring system. The A-ring is an aromatic benzene ring, substituted with a hydroxyl group, typical of an estrogen derivative. An ester linkage is present, connecting a deuterated fatty acid chain to the steroid core. The ester chain itself is a butanoyl group, with multiple deuterium atoms (D) replacing hydrogen atoms throughout the chain, including a fully deuterated methyl (CD3) end group. Stereochemistry is clearly indicated by wedge and dash bonds for specific hydrogen atoms and the methyl group.
