Zhou, Mi published the artcileBreed dependent regulatory mechanisms of beneficial and non-beneficial fatty acid profiles in subcutaneous adipose tissue in cattle with divergent feed efficiency, HPLC of Formula: 6217-54-5, the publication is Scientific Reports (2022), 12(1), 4612, database is CAplus and MEDLINE.

The current study aimed to determine whether breed and feed efficiency affect the mol. mechanisms regulating beneficial and non-beneficial fatty acid profiles in s.c. adipose tissue of beef steers. Fatty acid profiling and RNA-Seq based transcriptome anal. were performed on s.c. adipose tissues collected from beef steers with three divergent breeds (Angus, ANG, n = 47; Charolais, CHAR, n = 48; Kinsella Composite, KC, n = 48) and different residual feed intake (RFI, a measure of feed efficiency). The comparison of fatty acid profiles showed that KC had higher beneficial FAs compared to the other two breeds. Distinct FA profiles between H-RFIfat and L-RFIfat steers was more obvious for KC steers, where H-RFIfat steers tended to have higher proportion of healthy FAs and lower proportion of the unhealthy FAs. A higher number of differentially expressed (DE) genes were observed for KC steers, whereas ANG and CHAR steers had a lower number of DE genes between H- and L-RFIfat steers. The association analyses of the gene expressions and FA profiles showed that 10 FA metabolism-associated genes together with the one upstream regulator (SREBF1) were associated with the proportion of C18:2n-6, total n-6, PUFA and PUFA/SFA for KC steers but not the other two breeds. S.c. adipose tissue FA profiles and healthy FA index differed in cattle with divergent feed efficiency and such variation was unique for the three examined cattle breeds. Key FA metabolism-associated genes together with SREBF1 which is the upstream regulator of a set of genes involved in lipid metabolism may be of importance for genetic selection of meat with higher healthy FA index in beef cattle.

Wang, Qiuju published the artcileComparative study of female Chinese mitten crabs based on their sizes and weights, Related Products of catalysis-chemistry, the publication is Journal of Food Science and Technology (New Delhi, India) (2022), 59(7), 2572-2583, database is CAplus and MEDLINE.

The Chinese mitten crab (Eriocheir sinensis) is an important aquaculture species in China. While the price of a large crab will generally be 2-5 times higher than that of smaller crabs, it remains unknown whether nutritional quality is affected by market price. To investigate the effect of size on nutritional composition, adult female crabs were collected and assigned to grades I-IV according to decreasing size. The results showed that meat yield and conditional factors were significantly (P < 0.05) reduced with the decreasing size. The different sizes did not significantly (P > 0.05) affect levels of moisture, crude protein (except for hepatopancreatic crude protein), and total lipid. Grade III crabs had the largest hepatopancreatic crude protein level, which was significantly (P < 0.05) increased compared with grade I crabs. A balanced amino acid composition was found in grade IV crabs, while crabs from grades II and IV had the highest essential amino acids score. Levels of highly unsaturated fatty acids, including C22:6n3, and the ratios of n-3 polyunsaturated fatty acids (PUFA)/n-6 PUFA and C22:6n3 (DHA)/C20:5n3 (EPA) in the hepatopancreas were significantly (P < 0.05) increased in grade III crabs compared with the other grades. In conclusion, among the four grades smaller female crabs (average weight: 93-112 g, grades III-IV) displayed an optimal nutritional quality.

Zhang, Yan published the artcileA comparative study between freeze-dried and spray-dried goat milk on lipid profiling and digestibility, Quality Control of 6217-54-5, the publication is Food Chemistry (2022), 132844, database is CAplus and MEDLINE.

Different drying techniques impart distinguishing characteristics to goat milk, particularly to its fat globules. Here, we investigated the difference between freeze-dried and spray-dried goat milk (FGM and SGM) fat globules on lipid profiling and in vitro infant gastrointestinal digestibility. The former presented higher levels of MUFA (31.76%) and lower cholesterol content (1.20 ¡À 0.02 mg/g). Some important long-chain polyunsaturated triacylglycerols such as POL (16:0/18:1/18:2), PSL (16:0/18:0/18:2), and POO (16:0/18:1/18:1), also had better preservation in FGM. Moreover, we detected more species of lysophospholipid in FGM than SGM, accounting for 2.51% and 0.71% of total phospholipids, resp. More intriguingly, FGM, which has better membrane integrity and larger particle size, showed longer lag during gastric digestion and lower level of final lipolysis throughout gastrointestinal digestion. Therefore, our results showed the effects of different drying techniques on lipid profiling and digestibility of goat milk, providing significant insight for appropriate utilization of goat milk in infant nutrition.

Liu, Zhiqing published the artcileInvestigation of oyster Crassostrea gigas lipid profile from three sea areas of China based on non-targeted lipidomics for their geographic region traceability, Safety of Docosahexaenoic Acid, the publication is Food Chemistry (2022), 132748, database is CAplus and MEDLINE.

The present study sought to analyze the lipid profiles of oyster Crassostrea gigas from Yellow Sea (YS), East China Sea, and South China Sea (SCS) through the untargeted lipidomics strategy based on UPLC-Q-Exactive Orbitrap mass spectrometry and multivariate statistics. The results elucidated that geog. differences had profound effects on the lipid content, composition, and lipid mol. profiles. Notably, oysters from the YS group contained the highest lipid content, including triacylglycerol, diacylglycerols, and the majority of phospholipid mol. species, while oysters from the ECS group contained most of the phosphatidylcholine species and the SCS group contained most of the sphingolipid species. Totally, 1155 lipid mol. species belonging to 21 subclasses were identified; of them, 45 lipid mol. species could serve as differential marker for lipid of oysters from different sea areas. Overall, lipidomics could be a potential approach for discrimination of lipid characters between marine shellfishes for geog. origin traceability.

Wang, Zhangtie published the artcileImpact of interactions between whey protein isolate and different phospholipids on the properties of krill oil emulsions: A consideration for functional lipids efficient delivery, Computed Properties of 6217-54-5, the publication is Food Hydrocolloids (2022), 107692, database is CAplus.

The interactions between different phospholipids (yolk phospholipid, soybean phospholipid, and perilla seed phospholipid) and whey protein isolate (WPI) were studied. Phys. characteristics and bioaccessibility of different emulsions were compared. According to the results of multiple spectroscopy, isothermal titration calorimetry (ITC), and mol. docking, hydrophobic interactions played an important role in the interaction of phospholipid and WPI, enhanced as more unsaturation Dynamic light scattering showed that combination of phospholipids and proteins could decrease particle sizes (from 232.33 ¡À 4.79 nm to 188.59 ¡À 2.61 nm) and improve emulsion stability significantly (from -34.26 ¡À 1.31 mV to -49.13 ¡À 1.91 mV), presenting dose-dependency. Microstructure results indicated that phospholipids would contribute to dispersity and homogeneity of emulsions. Furthermore, the phospholipid-WPI emulsion can be an efficient tool for functional lipid delivery and improving the functional lipid ratios in the zebrafish model. Compared to WPI emulsions, the phospholipid-WPI emulsion group exhibited higher ratios of functional lipids in zebrafish fatty acid compositions (up to 29.41% ¡À 0.87%). In vitro digestion supported that perilla seed phospholipid-WPI emulsions would contribute to a higher bioaccessibility of EPA (from 36.59% ¡À 0.88%-53.08% ¡À 0.96%), DHA (from 36.42% ¡À 1.03%-54.10% ¡À 1.07%) and astaxanthin (from 31.54% ¡À 2.52%-53.31% ¡À 4.05%). Overall, our research can be useful to an efficient delivery system for functional lipids with phospholipid-protein structures.

Wu, Weida published the artcileCharacterization and identification of pork flavor compounds and their precursors in Chinese indigenous pig breeds by volatile profiling and multivariate analysis, Category: catalysis-chemistry, the publication is Food Chemistry (2022), 132543, database is CAplus and MEDLINE.

Chinese indigenous pigs are favored for their rich flavor, which is generated through complex reactions involving lipid-oxidation-related flavor precursors. In this research, we characterized the aroma compounds and fatty acids of representative Chinese pig breeds by gas chromatog.-olfactometry-mass spectrometry (GC-O-MS) and GC-ion mobility spectrometry (GC-IMS) with multivariate anal. A total of 79 volatile compounds were identified, among which 15 compounds were selected as odorants in pork. According to multivariate statistical anal., some odorants, including hexanal, 1-octen-3-ol, 2,3-octanedione, (E, E)-2,4-decadienal and dodecanal could be discriminative compounds explaining breed-originated differences in flavor profiles. As confirmed by partial least squares regression (PLS-R), some fatty acids, including C18:1n9c, C22:6n3 and C18:3n3, were major precursors for the formation of rich flavor in indigenous pig breeds. These results revealed that fatty acids and volatile compounds were breed-dependent, and the differences in flavor were related to the variance in the fatty acid content.

In order to further explain the fillet texture improvement of Yellow River carp (Cyprinus carpio) fed with faba bean (Vicia faba L.), a three-month rearing trial was conducted to investigate fatty acid composition, antioxidant capacity, myofiber development, collagen deposition and transcriptome in white muscle of two farmed carp groups (One was fed only faba bean, the other was fed com. diet). As a strong oxidant, faba bean changed fatty acids composition in white muscle, especially DHA and EPA, up-regulated the levels of reactive oxygen species (ROS) and down-regulated major antioxidant enzyme activities in the hepatopancreas and white muscle. Through the anal. of transcriptome and subsequent verification anal., we speculated that the increase of ROS led to the decrease of myofiber diameter and collagen metabolism This study provides a theor. basis for further understanding the regulation of faba bean on fillet texture characteristic of Yellow River carp.

Through monitoring Rancimat induction time (RIT), peroxide value (POV), and thiobarbituric acid-reactive substances (TBARS) of docosahexaenoic acid (DHA) algae oil and walnut oil during accelerated storage, the effects of the single and the combinations of seven kinds of antioxidants involving ascorbyl palmitate (AP), phytic acid (PA), vitamin E (VE), antioxidant of bamboo leaves (AOB), rosemary extract, tea polyphenols (TP), and tea polyphenol palmitate (TPP) against lipid oxidation were evaluated. RIT, POV, and TBARS results showed that the DHA algae oil sample containing 600 mg/kg TPP revealed the strongest stability and the walnut oil sample containing 450 mg/kg TPP and 100 mg/kg TP revealed the strongest stability. Then, the shelf lives of two oils were predicted from the extrapolation of the linear regression model between Log RIT and temperature Our results indicated that the optimal antioxidant could prolong the shelf lives of DHA algae oil and walnut oil by 2.31- and 7.74-fold, resp.

Li, Dong published the artcileThallium(I and III) exposure leads to liver damage and disorders of fatty acid metabolism in mice, Formula: C22H32O2, the publication is Chemosphere (2022), 307(Part_1), 135618, database is CAplus and MEDLINE.

Thallium (Tl), a highly toxic and priority pollutant heavy metal, exposure can damage mitochondria and disrupt their function. The liver is the central organ that controls lipid homeostasis and contains a large number of mitochondria. So far, there is no study investigating the effects of Tl exposure on hepatic fatty acid metabolism Here, we showed that 10 ppm of Tl(I) and Tl(III) exposures for two weeks did not significantly affect the body weight and water/food intake in mice. However, it decreased the ratio of liver/weight and induced hepatic sinus congestion and hepatocyte necrosis. Inductively coupled plasma-mass spectrometry (ICP-MS) anal. revealed Tl accumulation in the liver. Gas chromatog.-mass spectrometry (GC-MS) results showed that Tl(I) exposure significantly increased hepatic C18:0 concentration, while significantly decreased the concentrations of C16:1n-7, C20:1n-9, C18:3n-6, and C20:2n-9. Tl(III) exposure significantly reduced hepatic concentrations of C20:0, C22:0, C20:1n-9, C18:3n-6, and C20:3n-6. In addition, Tl(I) exposure upregulated the genes related to antioxidation (HO-1, GPX1, and GPX4), fatty acid synthesis (FADS2 and Elovl2), and fatty acid oxidation pathway (PPAR¦Á, ACADM, ACADVL, ACAA2, and CPT1A) in the liver. Tl(III) exposure did not significantly affect the transcript levels of liver antioxidative/metabolic enzymes and fatty acid synthesis-related genes, but upregulated fatty acid oxidation pathway-related genes (CYP4A10 and CPT1A). These results suggest that Tl(I) and Tl(III) exposures can cause liver damage and disrupt hepatic fatty acid metabolism, which provide new insights into Tl exposure-induced energy depletion from the perspective of fatty acid metabolism

Weigand, Miranda R. published the artcileEnhancement of lipid signals with ammonium fluoride in negative mode Nano-DESI mass spectrometry imaging, Name: Docosahexaenoic Acid, the publication is International Journal of Mass Spectrometry (2022), 116859, database is CAplus.

Lipids play an important role in biol. Their structural diversity presents challenges for untargeted mass spectrometry imaging (MSI) and anal. techniques. Enhancing the lipid coverage of MSI experiments is an important step to understanding their role in biol. processes. Herein, we use nanospray desorption electrospray ionization mass spectrometry imaging (nano-DESI MSI) to explore the effect of ammonium fluoride (NH4F) as a solvent additive for enhanced detection of lipids in biol. tissues. Although fatty acids and phospholipids are readily observed in nano-DESI MSI, other lipid classes are difficult to detect due to their low abundance and low ionization efficiency. We have evaluated enhancement factors of lipids in neg. ionization mode in the presence of NH4F in the nano-DESI solvent. We observed a 10-110-fold enhancement in lipid signals detected as [M – H]- ions using 500¦ÌM NH4F in 9:1 methanol:water in comparison with 9:1 methanol:water, which is typically used in nano-DESI MSI experiments The observed signal enhancement is attributed to the efficient proton abstraction from lipids by F-. The enhancement factors observed for fatty acids are correlated to their interfacial pKa values. The optimized solvent composition enables sensitive imaging of both high- and low-abundance lipids without any adverse effect on the noise level. Overall, our results demonstrate a substantial improvement in sensitivity of nano-DESI MSI of lipids in biol. tissues when NH4F is added to the nano-DESI solvent.
