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.
