[Chronological parameters of carbohydrate utilization in the body].

The glycaemic index (GI) is reviewed as example of chronological parameters of carbohydrate utilisation. A food utilisation depends not only on nutrient composition and physical properties of food but also on body metabolism and physiological status including individual peculiarities, daily rhythm and other chronological characteristics of body connected with energy metabolism and biosynthesis of glycoproteins, phospholipids and nucleic acids. Such analytical approaches are very important for practice of human nutrition and animal feeding and also for critical analysis of "fashion" theories in nutrition.

[The ratio 3H/14C as an indicator of body adaptation to various dietary factors].

In experiments with Wistar rats was shown that ratio 3H/14C in tissues after ingestion of double labeled glucose can be used as indicator of metabolic effects of different dietary carbohydrates. Predominant utilization of glucose for lipid synthesis was determined in rats fed SKP (93.4% of oligosaccharides and dextrines) and absence this effect in rats fed dextrinomaltose (69% of maltose and 26.

[The effect of various types of dry starch syrup on the rate of glucose utilization in lipid, carbohydrate, and protein components of rat liver].

Effect of a diet, containing dextran maltose and dry starch syrup, on some patterns of liver tissue metabolism were studied in young Wistar rats within 30 days. The animals of Control Group 1 were kept on a diet containing corn starch as a source of carbohydrates; in Group 2 the starch was replaced by the dry starch syrup enriched with disaccharides and especially with maltose; the dry starch syrup added into the Group 3 diet containing mainly oligosaccharides and polymers with high levels of glucose residues. The label mixtures of 6-3N- and 6-14C-glucose as well as of 6-3H- and I-14C-glucose were administered into the animals on the day of death.

[Effect of carbohydrate structure on glucose utilization and biosynthesis of lipids, proteins and glucagon in rats].

It was established that utilization of labelled glucose depended on food carbohydrate structure. Saccharose increased 1.5-fold the labelling of lipids in the liver and lowered insignificantly glycogen labelling.
