Radiation chemical studies of protein reactions: Effect of irradiation liquid containing aromatic hydrocarbons and pH on viscosity

When protein is irradiated by γ-rays from a ⁶⁰Co source in various liquids containing aromatic hydrocarbons, such as benzene, naphthalene, and phenanthrene, the effect of the radiation varies with the irradiation liquids containing aromatic hydrocarbons. An empirical equation for the viscosity change was obtained. Protein irradiated by γ-rays from a ⁶⁰Co source in air showed the effect of pH on protein reactions. An empirical equation for the viscosity change was obtained.     

Radiation Chemical Studies of Protein Reactions: Effect of Amino Acids,Proteins, Vitamins,Chelating Agents,S-Containing Compounds,and Temperature on Viscosity

Amino acids, proteins, vitamins, chelating agents, and S-containing compounds were found to protect the shape of the external envelope of the protein molecule from radiation damage. The behavior of the viscosity change closely resembles that found with sodium glutamate and sodium benzoate, as shown by a similar dependence on the concentration. Protein irradiated by γ-rays showed the effect of temperature on changes in the shape of the external envelope of the protein molecule. The behavior of the viscosity change was studied.     

Radiation Chemical Studies of Protein Reactions: Effect of Chelating Agents on the Breaking of Secondary Bonding in Protein

The radiation protective effect of the breaking of secondary bonding in proteins was examined with 1,2 diamine and 1,2 dihydroxy derivatives such as ethylenediamine, ethylenediaminetetraacetic acid, and propylene glycol, and monosubstituted amines and alcohols such as ethylamine and n-propyl alcohol. An empirical equation for the viscosity change was obtained.     

Radiation Chemical Studies of Protein Reactions: Effect of Irradiation Liquids Containing Aromatic Hydrocarbons and pH on Optical Rotation

When protein in various liquids containing aromatic hydrocarbons, such as benzene, naphthalene, and phenanthrene, is irradiated by γ-rays from a ⁶⁰Co source the changes in the internal relationships of the atoms in the protein molecule vary with the irradiation liquids containing aromatic hydrocarbons. An empirical equation for the optical rotation was obtained, and the phenomena were explained on the basis of the molecular mechanism.

Radiation Chemical Studies of Protein Reactions: Effect of Amino Acids and Vitamins on the Breaking of Secondary Bonding in Protein

The radiation protective effect of the breaking of secondary bonding in protein was examined with such amino acids as disodium inosine-5′ -monophosphate and disodium guanosine-5′ -monophosphate and vitamins such as thiamine and λ-ascorbic acid. The behavior of the viscosity change closely resembles that found with the sodium 1-glutamate as shown by a similar dependence on concentration.
