Effects of vitamins, coenzymes and amino acids on reactions of homolytic cleavage of the O-glycoside bond in carbohydrates.

It has been established that vitamins B1, K3 and C, coenzyme Q0 and amino acids cysteine and histidine effectively inhibit reactions of homolytic cleavage of the O-glycoside bond, which are responsible for the destruction of di- and polysaccharides on gamma-irradiation or the action of other reactive radical initiators. This effect was shown to originate from either oxidation or reduction of the radicals of carbohydrates undergoing destruction.

Long-range intermolecular interaction between broken DNA fragments.

We analyzed the long-range intermolecular interaction between fragments of broken DNA. We considered two constituents of long-range intermolecular interaction. The first is a net electrostatic Coulomb interaction between charges, involved in a structure of opposite nucleotides, which we evaluate using Debye-Huckel theory.

In this review the analysis of chemical structure of soybeans is given, are indicated and the outcomes of evaluation of medical and preventive efficiency of use soy and products of its processing in a feed of the patients with cardiovascular diseases on data of experimental researches and clinical natural observations are discussed.

Peculiarities of long-range interaction between the nucleotides after DNA damage.

In this work, the long-range interaction between the pairs of nucleotides situated on the opposite ends of a double broken DNA helix have been studied theoretically. The long-range energy was considered as a sum of electrodynamics Van der Waals and electrostatic Coulomb interactions. The most important region for the problem under consideration is about 5-15 A between the nucleotides.
