Abstract

Abstract : Sinapate esters are used throughout the plant kingdom, for example in photoprotection from ultraviolet radiation. Abstract : Sinapate esters are used throughout the plant kingdom, for example in photoprotection from ultraviolet radiation. Sinapate esters are naturally produced in their E -isomeric form; however, upon exposure to ultraviolet radiation, photoisomerization drives Z -isomer formation. To elucidate the photoprotection capacity of E vs. Z forms of sinapate esters, we explore the photochemistry of the model system, Z -ethyl sinapate. Following a novel Z -ethyl sinapate synthesis, we demonstrate that photoprotection is isomer independent. This suggests that, regarding photoprotection, there were no evolutionary pressures for biosynthesis of either isomer.
