[Proton permeability and electric breakdown of phospholipid membranes after UV-irradiation]. 1981

A V Putvinskiĭ, and T V Puchkova

Lipid peroxidation induced in bilayer lipid membranes (BLM) by UV-irradiation leads to two types of effects: selective in proton permeability and electric breakdown of the membranes. Both phenomena are always observed but the contribution of each in the membrane conductivity increase depends on the lipid nature (degree of unsaturation of fatty acids) and the value of transmembrane applied to BLM or generated by the membrane itself.

D011522 Protons Stable elementary particles having the smallest known positive charge, found in the nuclei of all elements. The proton mass is less than that of a neutron. A proton is the nucleus of the light hydrogen atom, i.e., the hydrogen ion. Hydrogen Ions,Hydrogen Ion,Ion, Hydrogen,Ions, Hydrogen,Proton
D014466 Ultraviolet Rays That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
