Dietary supplements of stearic, palmitoleic, and linoleic acids, as representative of saturated, mono-unsaturated, and polyunsaturated fatty acids, respectively, did not appreciably affect the relative composition of fatty acids in waxmoth larvae. Frass analysis demonstrated that most of the fatty acids in excess of their relative composition in the insect are excreted and speculations are made as to the possible mechanism involved in the retention of the characteristic fatty acid pattern.

Abstract The fatty acid composition in the lipids of six coccoid microalgae species (≈ 2 μm in diameter) was investigated. In addition to analyses of ultrastructure and pigment content, lipid composition is shown to be a chemotaxonomic tool in the classification of algae. The four species of Chiorococcales (Chlorophyceae) - the marine species as well as the fresh water species, both kept in artificial seawater - contain a fatty acid composition resembling that of Chlorella spp. and of green leaves of higher plants. The fatty acid pattern is characterized as lacking in C20 acids but containing large amounts of C 16 and C 18 polyunsaturated fatty acids, hexadecatrienic acid (16 :3) and a-linolenic acid (18:3ω3) in particular. In contrast the two species of Eustigmatales (Eustigmatophyceae) investigated here show a deficiency of the C 16 and C 18 polyunsaturated fatty acids but contain large amounts of eicosapentaenic acid (20:5).

Introduction. Polyunsaturated fatty acids show a wide spectrum of biological activity in human body, including lowering blood cholesterol level, arterial pressure, improving blood circulation, take part in prostaglandins synthesis etc. Thus, the search of new herbal sources of polyunsaturated fatty acids is an important task of modern pharmaceutical science aimed at creation of effective Ukrainian medicines and dietary supplements on their basis.The aim of the study – to learn of qualitative composition and quantitative content of fatty acids in garlic leaves and bulbs.Research Methods. The fatty acid composition of garlic leaves and bulbs was carried out using gas chromatography.Results and Discussion. As a result of the research 13 fatty acids were identified and their content was determined in garlic leaves, and 11 fatty acids – in garlic bulbs. Among the saturated fatty acids palmitic acid dominated in the leaves – 17.85 % and in bulbs – 13.67 %, and among unsaturated ones – linoleic acid – 46.40 % and 64.45 % respectively. The sum of unsaturated fatty acids both in the leaves and bulbs prevailed over the sum of saturated ones, which allows to expect hypocholesteremic, hypolipidemic, antiaggregant and hypotensive activity in the medicines containing the studied plant material types.Conclusions. 1. The fatty acid composition of garlic leaves and bulbs was carried out using gas chromatography. As a result of the research 13 fatty acids were identified and their content was determined in garlic leaves, and 11 fatty acids – in garlic bulbs. The sum of unsaturated fatty acids both in the leaves and bulbs prevailed over the sum of saturated ones, with prevalence of linoleic acid – 46,40% in the leaves and 64.45 % in bulbs. The obtained results allow recommending garlic leaves and bulbs as herbal source of polyunsaturated fatty acids with the following creation of effective Ukrainian medicines and dietary supplements on their basis.

Characteristic Fatty Acid

In contrast with many other insects, whose characteristic fatty acid compositions are influenced to a limited extent by dietary fatty acid composition, the fatty acid composition of the total lipid of the ichneumonid parasite Exeristes comstockii is very similar to that of its diet, that is, the host on which it is reared. When the parasite was reared on two hosts, Lucilia sericata and Galleria mellonella, with very different fatty acid patterns, it retained no characteristic fatty acid composition of its own.Radioisotope studies demonstrated that Exeristes comstockii, Galleria mellonella and Lucilia sericata incorporate 14C from 14C-1-acetate into fatty acids with radioactivity distributions consistent with de novo, elongation, and desaturation synthetic mechanisms.Exeristes comstockii was found to incorporate 14C-1-acetate into fatty acids at higher rates than either host. It appears, therefore, that the parasite has a fatty acid metabolism of its own, with respect to synthesis and turnover, although the fatty acids are qualitatively and quantitatively very similar to those in the host. The origin of the fatty acids of E. comstockii is partially explained by synthesis of fatty acids at different rates than its host, and direct incorporation of host fat, but the parasite appears to lack to great extent the control over pool size normally present in other insects.

1. The effects of dietary supplements of ω 3 polyunsaturated fatty acids on the fatty acid composition of platelets and plasma choline phosphoglycerides were studied in vegans and in omnivores.2. A supplement of 18:3ω3 led to an increase in 20:5 ω3 but was less effective than one of 20:5ω3+22:6ω3.

Abstract. Title of the paper: Investigations into the haem pigment content, reflection results as well as into the fatty acid pattern of the intramuscular fat of the Musculus longissimus dorsi (M.l.d.) Thuringian cattle, dependent on fattening system and genotype Haem pigment content, the reflection in visible range and the fatty acid pattern of intramuscular fat (imf) from minced musculus longissimus dorsi (m.l.d.) at the 8th / 9th dorsal vertebra of the right half of the carcass were determined in 35 cattle groups with bulls, steers and heifers, representing 19 different genotypes. The cattle were fattened indoors and/or outdoors at eight farms in Thuringia. The mean values of the haem pigment content varied between the animal groups from 6.3 to 13.1 mg/g fresh meat. A clearly lower variation was found in the maxima of reflectance at 415, 545 and 580 nm. The fatty acid composition of the imf was determined mainly by the fattening system. Fattening on pasture favoured high proportions of polyunsaturated fatty acids as well as a ratio of n6- to n3-fatty acids of < 10. The imf-content was positive correlated to the proportion of C18:1 and monounsaturated fatty acids (R = 0.4** / 0.5**) as well as negative to the proportion of polyunsaturated fatty acids (R = −0.7**).

AbstractThis study investigated the efficiency of growth and the carcass characteristics of 24 Greyface (Border Leicester × Scottish Blackface), 24 Texel (12 purebred and 12 Texel × Texel-Greyface) and 24 Rouge (12 purebred and 12 Rouge × Rouge-Greyface) lambs finished on the same level of feeding. The efficiency of live-weight gain (kg/MJ) was higher in Greyface compared with Texel lambs (P< 0·01). The efficiency of empty body-weight gain (kg/MJ) was higher in Greyface (P< 0·01) and Rouge (P< 0·05) compared with Texel lambs. The efficiency of carcass gains (kg/MJ) tended to be higher in Greyface and Rouge compared with Texel lambs (P= 0·07). The efficiency of non-carcass component gains (kg/MJ) was also higher in Greyface compared with Texel lambs (P0·05). Carcass water, protein, lipid and ash gains did not vary significantly between the genotypes, however carcass energy gain tended to be higher in Greyface and Rouge compared with Texel lambs (P= 0·08). The relative proportions of water, protein, lipid and ash in carcass gains did not vary significantly between the genotypes. At the end of the experiment carcass water content was higher in Texel compared with Greyface lambs (P< 0·05) and carcass ash content was lower in Texel compared with Greyface (P< 0·01) and Rouge (P< 0·05) lambs. The concentration of saturated fatty acids was higher in Greyface compared with Rouge lambs (P< 0·001) and higher in Rouge compared with Texel lambs (P< 0·05). Monounsaturated fatty acid concentrations were higher in Rouge compared with Greyface lambs (P< 0·05) and higher in Texel compared with Rouge lambs (P< 0·001). Polyunsaturated fatty acid concentrations were higher in Rouge and Texel compared with Greyface lambs (P< 0·01). The ratio of n-6:n-3 fatty acids was lower in Rouge compared with Greyface lambs (P< 0·05).The efficiency of empty body gain was higher in male compared with female lambs (P< 0·05). Carcass water (P< 0·01) and protein (P< 0·05) gains were higher in male lambs. At the end of the experiment male carcasses contained a higher content of water (P< 0·05), protein (P< 0·01) and ash (P= 0·07), and a lower lipid (P< 0·05) and energy (P< 0·001) content. Carcass lipids from male lambs contained a higher concentration of polyunsaturated fatty acids (P< 0·001) and tended to contain a lower concentration of saturated fatty acids (P = 0·06).
