BIOACTIVE COMPOUNDS IN HUMAN NUTRITION

Ilhomiddinova Shahrizoda Usmon qizi

Bioactive compounds are natural complexes containing minerals, vitamins, nutritional fibers, plant extracts, unsaturated fatty acids, amino acids. They eliminate deficiencies in nutrition, increase the absorption of healthy substances and increase the internal strength of the body, reducing the risk of many diseases. When nutraceuticals are added to food or drink, they enrich them with important substances (amino acids, vitamins, minerals, polyunsaturated fatty acids, dietary fibers, etc.) and support certain physiological functions of the human body and the systems of the human body regulates. They can be consumed in different forms (extracts, ointments, tinctures, concentrates.

ELECTROPHYSICAL AND SPECTRAL PROPERTIES OF A SOLID SOLUTION (GAAS)1−X(ZNSE)X GROWN FROM A LIQUID PHASE

Усманов Ш.Н., Гаймназаров К.Г., Даминов Р.Ш.

An epitaxial layer of a graded-gap solid solution (GaAs)1-x(ZnSe)x, 0<x<0.80 was obtained from a tin solution-melt bounded by horizontally arranged GaAs substrates. The composition and homogeneity of the solid solution have been studied. Some electrophysical parameters are given. The effect of gamma irradiation on the current-voltage characteristics of nGaAs-p(GaAs)1-x(ZnSe)x structures has been studied. It is shown that at irradiation doses up to 104 rad, the current-voltage characteristic of the studied structures improves, which is explained by a decrease in the concentration of actively working recombination centers due to the appearance of defect-impurity complexes.

PREPARATION AND POLYMERIZATION OF VINYL CHLORIDE

Narimova Venera Polatovna, Ibragimova Maftuna Lutfullo qizi

Vinyl chloride, CH2=CHCl — monochloroethylene, colorless gas. Molar mass 62.50; boiling point — 13.8°, melting point — 158.4°, density 983 kg/m3 (at 15°). Well soluble in chloroform, dichloroethane and ether, poorly soluble in water. Vinyl chloride is obtained by withdrawing one molecule of hydrogen halide from dihalide derivatives and attaching one molecule of hydrogen halide to acetylene hydrocarbons. Vinyl chloride is mainly used as a raw material in the production of polyvinyl chloride, various copolymers, vinylidene chloride and methyl chloroform.
