Triglyceride Fatty Acid

Muscle tissue of the queen crab, Chionoecetes opilio, contained 0.75% lipid, 78.8% of which was phospholipid (chiefly choline phosphatides) and the balance mainly cholesterol. Viscera contained 13.6% lipid, the bulk of which was triglyceride. Fatty acid composition was generally similar to that of other marine species. However, 20:5ω3 was the major polyunsaturate (rather than the more usual 22:6ω3) and within the 18:1 series, the ω7 isomer was present in unusually large quantities.

Abstract The fatty acid profiles of prime and “spent” (inferior quality) Chinook salmon (Oncorhynchus tshawytscha) and coho salmon (O. kisutch) have been determined. There are indications that the long chain monounsaturated acids are preferentially utilized by the migrating salmon. However, there may be larger generic and specific run variations that preclude the use of a fatty acid compositional approach to differentiate between prime and spent salmon.

This report from Golembeski and Emery adds to the small quantity of literature in this field. Drs Golembeski and Emery claim that they are presenting information that counters our statement,"The abnormalities in fatty acid composition of the cystic fibrosis milk may contraindicate its use for the nursing infant." However, no data regarding fatty acid composition were presented. In their Table, only total lipids are shown. In our study, we acknowledged that mean total lipids were sufficient to supply the energy needs of the nursing infant.

The sensitivity of Listeria monocytogenes Scott A and ATCC 19114 to antimicrobial compounds was altered when bacterial membrane lipid composition was modified by growth in the presence of added fatty acids. Analysis of cellular fatty acid composition by gas-liquid chromatography indicated that L. monocytogenes Scott A cells contained 0.97, 2.32, 0.81, and 0.72% (relative) of C14:0, C16:0, C18:0, and C18:l, respectively. In the presence of exogenously supplied C14:0, C16:0, C18:0, and C18:l, the percentages increased to 14.03, 30.92, 16.30, and 27.90%. Average MICs for L. monocytogenes Scott A and ATCC 19114 to sodium chloride, tertiary butylhydroquinone, methyl paraben, and propyl paraben were 10.0%, 81, 1406, and 544 μg/ml, respectively. Growing either strain in the presence of 50 μg/ml of either exogenously added C14:0 or C18:0 fatty acids increased their resistance to the four antimicrobial compounds. However, growth in the presence of C18:1 led to increased sensitivity to the antimicrobial agents. The results indicate that the susceptibility of L. monocytogenes to antimicrobial agents is related to the lipid composition of the cell membrane. Consequently, food preservation processes which alter fatty acid composition of L. monocytogenes could result in changes in antimicrobial susceptibility.

AbstractThe free fatty acid composition of the southern pine beetle, Dendroctonus frontalis Zimmermann, and associated bark beetles was determined by gas-liquid chromatography. The lipid composition of several species of hymenopterous parasites matched the bark beetle hosts from which they were reared. Lipids from field collected parasites were compared with the lipid composition of possible bark beetle hosts to determine host of origin. Parasites ovipositing on a host were usually found to have a lipid composition matching that host. Approximately 20% of the parasites that were observed attempting to parasitize the southern pine beetle apparently developed on other bark beetle hosts.

Fatty Acid Pattern

Abstract We previously reported that the sperm of rhesus monkeys and humans uniquely contain large amounts of desmosterol not found in other tissues and have a high concentration of the highly polyunsaturated n-3 fatty acid, docosahexaenoic acid (22:6 n-3). However, the lipid composition of the testis, from which sperm originate, is unknown. During puberty, the testis undergoes remarkable morphological changes as testosterone levels rise and sperm production begins. We hypothesized that testicular maturation might also involve dramatic changes in lipid composition. Accordingly, we characterized the sterol and fatty acid composition of the testis of rhesus monkeys throughout the lifespan, from birth to old age. Although the cholesterol content in the testis remained relatively unchanged throughout life, the desmosterol content first decreased from 59 μg/g in infants to 6 μg/g in prepubertal monkeys, increased to 83 μg/g during puberty, and reached a plateau of 248 μg/g in the young adult, where it remained into old age. The polyunsaturated fatty acid composition of the testis also changed markedly. Docosahexaenoic acid (22:6 n-3) increased from 5.1% of total fatty acids in infants and juveniles to 18.1% in postpubertal young adults. Although some n-6 fatty acids, arachidonic (20:4 n-6) and linoleic (18:2 n-6), decreased from 16.0% and 10.0% in prepubertal juveniles, respectively, to 7.1% and 3.3% in young adults; dihomogamma-linolenic acid (20:3 n-6), the precursor of 1 series PGs, increased greatly from 1.8% to 10.3%. Similar changes occurred in both membrane and storage lipids (phospholipids and triglycerides), respectively. After puberty, the testicular fatty acid pattern remained stable into old age. Our data demonstrated that puberty is accompanied by substantial changes in the lipid composition of the primate testis. These changes suggest that desmosterol and both n-3 and n-6 polyunsaturated fatty acids may have important roles in sexual maturation.
