Figure 2. Photooxidation of A2E and
all-trans-retinal dimer (at RAL dimer)monitored by UPLC with photodiode
array detection. A2E and atRAL dimer were irradiated at 430 nm for
indicates times. Absorbance peaks were normalized to intensity at 0
time. Inset; normalized absorbance peak area as a function of time.
Decreases in peak height and area reflect photooxidation-associated
consumption of the compound.
