UV-A induced lipid peroxidation in liposomal membrane.

Abstract

UV-A (365 nm) produced a dose-dependent linear increase of lipid peroxidation, as detected by the assay of malondialdehyde (MDA). MDA formation was inversely related to the UV-A dose rate. Sodium formate and ethylenediaminetetra acetic acid (EDTA) could not inhibit by any significant degree the UV-A induced MDA formation. While butylated hydroxy toluene (BHT) caused about 85% inhibition, sodium azide and L-histidine produced 45-50% inhibition of MDA formation. The involvement of singlet oxygen (1O2) in the UV-A induced lipid peroxidation is discussed.
