In the test tube, sodium linoleate and sodium linolenate kill and dissolve virulent pneumococci more rapidly and in higher dilutions than sodium oleate; otherwise their action is the same. The intensity of action on the cocci is directly proportional to the degree of unsaturation of the acid. Blood serum inhibits the bacteriolytic and hemolytic action of unsaturated soaps partially or completely, according to definitive quantitative relations between serum and soap. Small quantities of serum completely inhibit the action of dilute soap solutions, but even whole serum does not prevent bacteriolysis and hemolysis by relatively concentrated soap solutions, i. e. 1 per cent. and 0.5 per cent. A given quantity of serum inhibits the action of the soaps in inverse ratio to their degree of unsaturation. The hemolytic and bacteriolytic action of soaps of the unsaturated fatty acids is probably due in part to their avidity for protein and not wholly to their ability to dissolve lipoids. Attempts to prevent serum inhibition of the lytic action of sodium linoleate and sodium linolenate were unsuccessful. The more unsaturated soaps are not as efficient in preventing fatal pneumococcic infection of animals as sodium oleate.

The work shows the influence of the electromagnetic field of the microwave range (EMF microwave) on the variability of fatty acids and their derivatives in seedlings of corn of different ages. The object of the study was the corn seeds of the Belarusian selection of the Daria hybrid, which were treated with microwave EMF for 12 minutes with a frequency of 64–66 GHz, exposure power 10 mW. The control was untreated EMF microwave seeds. Fatty acids were determined by gas chromatography with mass spectrometry (GC-MS). Analysis of fatty acids and their derivatives, occurring in seedlings of corn of different ages, showed that in the roots and leaves of corn fatty acid metabolism goes in different ways. On the 4th day of growth, the content of the following oxylipins increases in maize seedlings: hydroxymethyl ester of linoleic acid and octadecanoic acid, 2,3-dihydroxy propyl ether by 57.8% and 26.8%, respectively. By the 12th and 14th day of growth, the content of α-linolenic acid, which is the starting material for the synthesis of oxylipins, substantially increases in the roots of corn. Also, unsaturated fatty acids predominate in the roots, saturated in the leaves. Under the influence of the electromagnetic field of the microwave range in the roots of corn, a decrease in the content of saturated and, accordingly, the degree of unsaturation of fatty acids increases. In leaves, on the contrary, there was an increase in the amount of saturated and a decrease in unsaturated fatty acids after EMF treatment of corn seeds. Polyunsaturated fatty acids, linoleic and linolenic, predominate in the seedlings, roots and leaves of corn. In this regard, it can be assumed that the stimulating effect of pre-sowing treatment of microwave EMF on germination, growth and development of corn occurs through the accumulation of unsaturated fatty acids and oxylipins as a response of the plant to exogenous exposure.

Commercial by supplied triacylglycerols and synthesized triacylglycerols were used in this project. Analysed triacylglycerols with the range of carbon number (CN) 24–54 consisted of saturated and unsaturated fatty acids. Two capillary columns were used in the analyses of triacylglycerols, namely non-polar (Optima<sup>®</sup>-1-TG) and medium polar (Optima<sup>®</sup>-17-TG) types. In this study the effectiveness of separation (A) of triacylglycerols with different carbon number values, (B) of triacylglycerols with different unsaturation degree, (C) of positional isomers were determined and further possibilities to separate another lipid compounds were analysed. The column Optima<sup>®</sup>-17-TG separates TAG according to the degree of unsaturation while the column Optima<sup>®</sup>-1-TG separates saturated and unsaturated TAG. High temperature capillary gas chromatography was used to determine changes in triacylglycerol composition during the transesterification of structured fats.

ABSTRACTBackfat from each of 25 littermate boars, barrows and gilts, which were crosses of the Large White and British Landrace breeds slaughtered at approximately 90 kg live weight, was analysed for fatty acid composition. Fat from boars had a significantly higher proportion of total unsaturated fatty acids (61·6%) compared with barrows (60·2%), This sex difference was due to a lower palmitic acid (16:0) content and higher linoleic (18:2) and linolenic (18:3) fatty acid levels in backfat of boars. Gilts were intermediate to boars and barrows in the degree of unsaturation of backfat.

The aim of study was to investigate the effect of RYR1 genotypes on carcass traits and lipid fractions in blood serum and musculus longissimus dorsi of Polish Landrace pigs. The fatteners with RYR1CRYR1 genotype had lower level of triglycerides, total cholesterol, HDL- and LDL cholesterol in blood serum than individuals from RYR1CRYR1C group. The same group of animals had lower amount of intramuscular fat and cholesterol in comparison to homozygotes RYR1CRYR1C. The intramuscular fat of heterozygotes contained less saturated fatty acids, but more unsaturated fatty acids including polyunsaturated acids. The RYR1 genotype had no significant effect on all studied traits in Polish Landrace fatteners.
