Radical behavior produced in-irradiated alanine and phenylalanine amino acids aqueous solutions

الملخص EN

Radiolysis of alanine and phenylalanine in aqueous solutions containing NADH has been carried out at different gas saturation and pH.

It has been found that the oxidation of NADH decreases by increasing pH.

Also, it has been observed that the yield of NADH oxidation in N2-saturated aqueous solutions is higher than that observed in oxygenated irradiated solution.

It is concluded that more oxidizing radicals are generated through the deamination process as a result of the electron addition on the ammo acid.

The results also have shown that the yield of NADH oxidation is higher slightly in the case of alanine as compared to that in the case of phenylalanine
