Abstract Field experiment was carried out in the fields in Al-Mahaweel district of Babil Governorate during the agricultural season 2020-2021 to estimate the effect of biological fertilization on the content of some fatty acids in flax varieties seeds. A factorial experiment was applied according to a Randomized Complete Block Design (R.C.B.D) with three replications. The experiment included two factors, the first included eight varieties of flax (Indian, Giza11, Giza10, Sahka5, Sahka6, Giza8, Syrian Thorshansity72), The second factor, biological fertilization included four treatments: (control, bacterial fertilization, fungal fertilization and a bacterial-fungal mixture). The fatty acids (a-Linolenic acid, Oleic acid, Linoleic acid, Palmitic acid, Stearic acid) in seeds were determined using HPLC High-Performance Liquid Chromatography. The results showed that Sahka6 Variety was significantly superior on other varieties in seed content of (Oleic acid and Linoleic acid) amounted to (29.70, 28.39) %, respectively, while Indian Variety superiority in seed content of Palmitic acid and Stearic acid amounted to (21.28, 25.27)% respectively. Bacterial fertilizer + Mycorrhiza were significantly superior to the other fertilizer treatments in all indicators of study, and the interaction between a variety and biofertilization did not show any significant differences except for the seed content of (a-Linolenic acid Palmitic acid).

Fatty Acid Peroxidation

The effect of methyl jasmonate (MJ) vapors on the composition and peroxidation of major fatty acids in the organs of common buckwheat seedlings was investigated. The composition of fatty acids in the hypocotyl and cotyledons of seedlings changed significantly under exposure to MJ vapors in closed jars. Four-day exposure to MJ led to a significant reduction in the concentrations of stearic, linoleic, and linolenic acids in the hypocotyl, whereas oleic acid levels increased approximately 3.5-fold. A decrease in stearic acid levels and an increase in the content of linolenic acid were noted in cotyledons, whereas oleic acid levels decreased in roots. Seven-day exposure to MJ vapor caused a further reduction in stearic acid content and an increase in oleic acid and linoleic acid levels in the hypocotyl. At the same time, the linoleic acid content of roots and linolenic acid levels in cotyledons were doubled, but a 5-fold reduction in linolenic acid concentrations was observed in roots. Methyl jasmonate intensified fatty acid peroxidation in cotyledons after 4 and 7 days and in roots after 4 days of exposure. Peroxidation was inhibited in the hypocotyl and roots after 7 days. The noted changes in the composition and peroxidation of fatty acids are probably indicative of senescence in buckwheat seedlings under the influence of MJ. Senescence seems to proceed faster in cotyledons than in other organs of buckwheat seedlings.

Overripe tempe is a food product that used by peoples in Indonesia as a food seasoning. So far, overripe tempe received less attention than fresh tempe and research of overripe tempe is rarely done. The objective of the study is to identify the fatty acid compounds of the  fifth day fermentation overripe tempe oil before and after purification . The overripe tempe oil of fifth day fermentation was extracted with soxhletation method using n – hexane solvent, then it was purified. The various fatty acids  of overripe tempe oil were analyzed by GC – MS. The purification process was done by using H3PO4 0,2% and NaOH 0,1N. The result of the study showed that before purification the oil  was composed of eight compounds  are palmitic acid (13,33%),  linoleic acid (77,57%), stearic acid (6,15%), and the five chemical components, Dasycarpidan – 1 - methanol, acetate ,  oleic acid, 9 - Octadecenamide ,Cholestane - 3, 7, 12, 25 - tetrol, tetraacetate, (3?, 5?, 7?, 12?) and  6, 7 – Epoxypregn – 4 – ene -9, 11, 18- triol - 3, 20 - dione, 11, 18 – diacetate have percentage of areas less than 3%. After purification the oil  was composed of palmitic acid (12,38% ), linoleic acid (80,35 %), stearic acid (5,84%), and 17 – Octadecynoic acid (1,42 %) .

Cold Tolerant

Three genotypes of seashore paspalum, `PI 299042', `Adalayd', and `PI 509018-1' considered to be cold-sensitive, intermediately cold-tolerant and cold-tolerant, respectively, were analyzed to investigate the biochemical basis of cold tolerance. The cultivars were acclimated to 8/4 °C day/night temperatures and rhizomes nodes and crowns were harvested at 7-day intervals over the 4-week experiment. Total lipid was extracted from these tissues, and the fatty acids present in the lipid fraction were identified by gas chromatography. Palmitic acid, stearic acid, linoleic acid and linolenic acid were the major fatty acids present. In cold acclimated tissues, the level of palmitic acid and stearic acid did not change significantly during the treatment period. There was a decrease in the level of linoleic acid by the second week of cold treatment. The amount of linolenic acid increased significantly during the second week of cold treatment corresponding to the decrease in linoleic acid. The change in the amount was significantly greater in `PI 509018-1' than in `Adalayd' or `PI 299042'. These results are similar to what was found for cultivars of bermudagrass that differ in their cold-tolerance phenotypes. Desaturases are enzymes involved in introducing the double bonds into the fatty acid chains. Research is underway to characterize and clone the genes encoding the Ω3, Ω6, and Ω9 desaturases, which may have an important role in affecting the cold tolerance by altering the degree of membrane lipid fatty acid saturation.

There are several underexploited plant seeds or fruits in Nigeria with little information about their chemical composition. To this end a comprehensive study on fatty acid, phospholipids and phytosterols composition of bitter melon (Momordica charaantia) fruit and ebony tree (Diospyros mespiliformis) fruit pulp were determined using standard analytical techniques. The most concentrated fatty acid (%) was linoleic acid in Momordica charantia fruit (45.47) and 44.82 in Diospyros mespiliformis fruit pulp. The increasing order of the concentrated fatty acids in Momordica charantia fruit were: linolenic acid (2.38) < stearic acid (7.52) < oleic acid (20.18) < palmitic acid (23.64) < linoleic acid (45.47) while that of Diospyros mespiliformis fruit pulp were: linolenic acid (5.73) < stearic acid (8.62) < oleic acid (18.95) < palmitic acid (20.88) < linoleic acid (44.82). Arachidonic, arachidic, palmitoleic, margaric, behenic, erucic, lignoceric, myristic, lauric, capric and caprylic acids were present in small quantities with none of them recording up to 1.0% in both of the two samples. The results also showed low concentration of monounsaturated fatty acids (MUFA) (20.41%) in Momordica charantia fruit and 19.13% in Diospyros mespiliformis fruit pulp, and values of polyunsaturated fatty acid (PUFA) were 2.44 and 5.78% for the two samples, respectively. The respective phospholipids composition showed a highest concentration of phosphatidylcholine in Momordica charantia and Diospyros mespiliformis (100.31and 88.12 mg/100 g) while lysophosphatidylcholine and phosphatidic acid were the least concentrate values of 12.62 and 14.52 mg/100 g in Momordicacharantia and Diospyros mespiliformis, respectively. The concentrations of phytosterols were of low values except in sitosterol with values of 153.28 and 119.46 mg/100 g in Momordica charantia and Diospyros mespiliformis, respectively. This study provides an informative lipid profile that will serve as a basis for further chemical investigations and nutritional evaluation of Momordica charantia fruit and Diospyros mespiliformis fruit pulp.

Rat Adipocytes

The effects of inclusion of different fatty acids in the medium on the rate of esterification of palmitic acid and its stereospecific distribution among the three positions of the triacyl-sn-glycerols by preparations of rat adipocytes in vitro have been determined. Myristic acid, stearic acid, oleic acid and linoleic acid were used as diluents and the concentration of the combined unesterified fatty acids in the medium was held constant; only the proportion of palmitic acid was varied. The amount of palmitic acid esterified was always linearly related to its relative concentration in the medium and was not significantly affected by the nature of the diluent fatty acid chosen. Constant relative proportions were recovered in triacylglycerols and in intermediates in each instance. The amount of palmitic acid esterified to each of the positions of the triacyl-sn-glycerols was linearly dependent on the relative proportion in the medium but the nature of the relationship was markedly influenced by which fatty acid was present. When stearic acid was present, simple relationships were found over the whole range tested. When either myristic acid, oleic acid or linoleic acid was present, abrupt changes in the manner of esterification of palmitic acid were observed in position sn-1 when the relative concentrations of palmitic acid and the diluent reached critical values, which differed with each fatty acid. In position sn-2 when oleic acid or linoleic acid was present, a similar change was observed, and in position sn-3 it was obtained with myristic acid as diluent. The results are discussed in terms of changes in the relative affinities of the acyltransferases for palmitic acid. Palmitic acid was esterified into various molecular species in proportions that indicated acylation with non-correlative specificity at higher relative concentrations but not at lower.

Fatty Acid Analysis

Phosphatidyl ethanolamine and phosphatidyl serine extracted from dog bile have been separated by means of ammonium silicate column chromatography. Concentration of phosphatidyl serine in dog bile is about seven times higher than phosphatidyl ethanolamine. Fatty acid analysis by gas chromatography showed that phosphatidyl ethanolamine contains about 26% palmitic acid, 18% stearic acid, 11% linoleic acid, 2% linolenic acid, 9% arachidonic acid, 3% C22:5 fatty acid, and 6% C22:6 fatty acid. The concentrations of these fatty acids observed in phosphatidyl serine are different; palmitic acid represents about 43%, stearic acid 9%, linoleic acid 24%, linolenic acid a trace amount, and arachidonic acid 5%; C22:5 and C22:6 fatty acids are absent.

Saturated Fatty Acids

In the last decades many researches were made to change the animal product food’s composition. The production of better fat-compound milk and dairy products became a goal in the name of health conscious nutrition. These researches were motivated by the non adequate milk fat’s fatty acid composition. There have been made researches in order to modify the milk’s fatty acids’ composition to reach the expectations of functional foods. With the optimal supplement of the feed can be increased the proportion of the polyunsaturated fatty acids and can decreased the saturated fatty acids. Row fat content of milk was not decreasing in the course of examination neither of the cold extruded linseed nor the whole linseed supplement as opposed to observations experienced by other authors. In case of monounsaturated and polyunsaturated fatty acids when supplementing with cold extruded linseed the most significant change was observable in the concentration of the elaidic acid, oleic acid, linoleic acid, alfa-linolenic acid, conjugated linoleic acid. In case of saturated fatty acids the quantity of palmitic acid and myristic acid lowered considerably. When observating the feeding with whole linseed the concentration of many fatty acids from the milkfat of saturated fatty acids lowered (caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid). The quantity of some unsaturated fatty acids was showing a distinct rise after feeding with linseed, this way the oleic acid, alfa-linolenic acid, conjugated linoleic acid, eicosadienoic acid. The aim of the study was to produce food which meets the changed demands of customers as well. The producing of milk with favourable fatty acid content from human health point of view can give scope propagate the products of animal origin.
