The Calvin Benson Cycle

Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...

  • Structure elucidation using 1D and 2D Nuclear Magnetic Resonance (NMR) spectroscopy.
  • Structure confirmation using mass spectrometry (MS) and comparison with literature data.

    • Main Results:

    • Two new rotenoids, designated boerharotenoids A (1) and B (2), were isolated and characterized.
    • Four known compounds, boeravinone (3), 5,7,3'-trihydroxycoumaronochromone (4), boeravinone F (5), and eupalitin-3-O-beta-D-galactopyranoside (6), were also identified.
    • The structures of all isolated compounds were definitively established through comprehensive spectroscopic analysis.

    Conclusions:

    • The study successfully identified novel rotenoids and known compounds from Boerhavia repens.
    • The structural elucidation provides valuable phytochemical data for this plant species.
    • These findings lay the groundwork for investigating the potential biological activities of these isolated compounds.
