of its polypeptide chain is located on the outer surface of the membrane [K. C. Chaudhary, M. S. Nijjar., 1988] affects the function of cilia of ciliary cells of the epithelium. The obtained data on the localization and activity of the AC allow us to conclude that in intact rats in the mucosa the greatest activity of the adenylate cyclase is found on the surface of the cilia of the single-layered multi-row ciliated epithelium and on the surface of the endothelium of the blood capillaries of the submucosa of the trachea. As for the activity of adenylate cyclase in the experiment, with prolonged cold exposure, the intensity of its work in the ciliated epithelium of the mucosa decreases. Conversely, there is an increase in the activity of the active center on the surface of the endothelium and erythrocytes in the submucous capillary capillaries. Assessing the function of the ciliated epithelium, especially in the situation with cold exposure, it is necessary to pay attention to the concentration of cyclic nucleotides, which determine pathological changes in the mucociliary conveyor. Abstracts: The article presents the results of studying the effect of arabinogalactan extracted from larch Daurskaya on the formation of the properties of the fermented milk product. The optimal dose of introducing arabinogalactan into the composite mixture was determined. ReferencesKey words: functional food products, probiotic, prebiotic, arabinogalactan, fermented product.When producing dihydroquercetin from larch, a significant amount of biologically active substances can be obtained as a byproduct. One such biologically active substance is arabinogalactan.From the middle of the last century domestic and foreign scientists have been studying its structure and properties. Arabinogalactan is found in immunomodulating herbs (Echinacea purpurea, Baptisia tinctoria, Angelica Acutiloba, and Curcuma longa), but the study of the arabinogalactan extracted from larch is of the greatest interest, since it constitutes a significant part of its biomass. The heartwood of some species of larch comprises up to 35% of arabinogalactan [1].In recent years, the study of the biological activity of arabinogalactan has been intensified. The difference of arabinogalactan from many polysaccharides has been reported in terms of physico-chemical properties such as low viscosity of concentrated aqueous solutions, high solubility in water, resistance to acid environment, thermal and hydrolytic stability, and good dispersing ability [2]. It was found that arabinogalactan has a significant membranotropic and antimicrobial action against certain bacteria as well as immunomodulating property [3, 4] and antimutagenic activity [4].The prebiotic ability is of particular interest in studying the properties of arabinogalactan. The results of studies of foreign and domestic scientists show the effect of larch arabinogalactan as a nutrient medium for Lactobacilli and Bifidobacteria since it is a fermentable fiber.Arabinogalactan serves as food to beneficial symbiotic ba...
