Monoglycerides are widely used in flour-based products, but the roles of their dispersibility and acyl chain length remain unclear. This study investigated the effects of monoglycerides with different chain lengths (C12, C16, C18) dispersed in deionized water (DW) or 95 % ethanol (EE) on fresh noodle quality. Ethanol (2 mL per 200 g flour) had no significant effect on noodle properties, but monoglycerides in EE significantly altered gluten structure through covalent and non-covalent interactions, forming a denser gluten network, as observed by CLSM. Starch-lipid complex formation was confirmed by FT-IR, Raman, and XRD, enhancing cooking and immersion performance. Monoglycerides in EE were more effective than in DW, with impact orders: DW (C12 > C16 ≈ C18) and EE (C12 < C16 < C18), indicating solvent selection was more critical than chain length. This study refined the application method of monoglycerides, enhancing their functional performance and contributing to elevated noodle performance.

Frequent and extreme drought exerts profound effects on vegetation growth and production worldwide. It is imperative to identify key genes that regulate plant drought resistance and to investigate their underlying mechanisms of action. Long-chain fatty acids and their derivatives have been demonstrated to participate in various stages of plant growth and stress resistance; however, the effects of medium-chain fatty acids on related functions have not been thoroughly studied.

Herein we report the synthesis of a novel di-O-acylated DNJ derivative, conceived to study whether iminosugar derivatization with a lipophilic acyl moiety could positively affect its antibacterial properties. The well-known PS-TPP/I/ImH activating system was used to readily install the acyl chains on the iminosugar, leading to the desired compound in high yield. Biological assays revealed that a di-O-lauroyl DNJ derivative enhanced the antibacterial effect of gentamicin and amikacin against S.

Background: The inheritance of the short allele, encoding the serotonin transporter (SERT) in humans, increases susceptibility to neuropsychiatric and metabolic disorders, with aging and female sex further exacerbating these conditions. Both central and peripheral mechanisms of the compromised serotonin (5-HT) system play crucial roles in this context. Previous studies on SERT-deficient (Sert) mice, which model human SERT deficiency, have demonstrated emotional and metabolic disturbances, exacerbated by exposure to a high-fat Western diet (WD).

Background/objectives: The pathogenesis of metabolic dysfunction-associated steatohepatitis (MASH) is closely associated with increased oxidative stress and lipid peroxidation. Coenzyme Q (CoQ) and selenium (Se) are well-established antioxidants with protective effects against oxidative damage. This study aimed to investigate the effects of CoQ and Se in ameliorating MASH induced by a methionine choline-deficient (MCD) diet in mice.

Five types of frankfurters were formulated: a control without tamarind (T0) and four samples using 5% tamarind pulp paste (PT5), seeds (ST5), peel (CT5), and a blend of all of them (PSCT5), replacing the same portion of meat. The inclusion of tamarind components led to a reduction in the moisture and protein content of the reformulated frankfurters. In terms of mineral composition, CT5 showed the highest ( < 0.
