Metabolic-associated fatty liver disease (MAFLD) represents a spectrum of hepatic disorders characterized by excessive lipid accumulation in the liver with a global prevalence rate of 30%. Despite their increasing prevalence, current therapeutic interventions remain suboptimal, constrained by substantial adverse effects and prohibitive treatment costs. Through an a...
Continue readingFor flavan-3-ols, significant effects to prevent the development of diabetes mellitus are postulated. Inter alia, this is attributed to inhibitory effects on the intestinal α-amylase, in particular for high-molecular-weight procyanidins. In order to gain a deeper insight into the mode of interaction and the resulting α-amylase inhibition, the interactio...
Continue readingOvomucoid (OVM) is the most abundant trypsin inhibitor in egg white, considered as one of the anti-nutritional factors in egg processing. In this study, the molecular mechanism of the interaction between OVM and trypsin was explored. Besides, the effect of food processing methods on the activity of OVM and structural change of OVM was analyzed. The results showed...
Continue readingPectin, a soluble fiber, can induce elongation of the intestinal villi. However, the relationship between pectin-induced villus elongation and nutrient absorption remains unclear. Therefore, we investigated whether pectin could mitigate malnutrition by enhancing nutrient absorption. We specifically utilized Yuzu pectin side chains, which were chosen for their poten...
Continue readingThe good phytotoxicity and selectivity against weeds versus tomato or cress make saponin-rich fractions from Agave macroacantha, A. colorata, A. parryi, and A. parrasana attractive candidates as bioherbicides. The saponin contents have only previously been reported for A. macroacantha, and as a consequence, simultaneous dereplication has been performed on saponin-r...
Continue readingFish is well known for its perishable nature. Essential oils in food packaging seem to be safe and reliable both in terms of safety for the consumer and in terms of improving the shelf life of the product. This study aimed to evaluate the effects of two different essential oil vapours (one with rosemary and the other one with lemon extract) on three different typ...
Continue readingAlcohol dehydrogenase (ADH) is a crucial rate-limiting enzyme in alcohol metabolism. Our previous research found that ethanol-induced intracellular extracts of Lactococcus lactis (L. lactis) could enhance alcohol metabolism in mice, but the responsible compounds remain unidentified. The study aimed to screen potential ADH-activating peptides from ethanol-induced L....
Continue readingRecent years have witnessed an increasing interest in the synthesis and study of BODIPY-glycoconjugates. Most of the described synthetic methods toward these derivatives involve postfunctional modifications of the BODIPY core followed by the covalent attachment of the fluorophore and the carbohydrate through a “connector”. Conversely, few de novo synthe...
Continue readingTwo new terrein derivatives, aspergilethers A and B (1 and 2), two known analogues (3 and 4), and three known butenolides (5–7) were isolated from the endophyte Aspergillus terreus HT5. Their structures were determined by spectroscopic analysis and ECD and NMR calculations. Interestingly, 1 and 2 had unpresented medium aliphatic side chains in terrein derivat...
Continue readingAn aspartate peptidase with proteolytic activity toward gluten was identified from an isolated red yeast Rhodotorula mucilaginosa strain. This peptidase consists of 425 amino acids, comprising an N-terminal signal peptide, a propeptide, and a C-terminal catalytic domain. The catalytic domain, termed RmuAP1CD, could be secreted by the recombinant oleaginous yeast Ya...
Continue readingIron is one of the trace mineral elements, and iron deficiency is a common phenomenon that negatively influences human health. Food-derived iron supplements were considered excellent candidates for improving this syndrome. In this work, oyster-protein hydrolysates (OPH) and ferrous chloride successfully formed the OPH–Fe complex (6 mg/mL, 40 °C, 30 min), ...
Continue readingβ-Glycosidase from Sulfolobus solfataricus (SS-BGL) is a highly effective biocatalyst for the synthesis of compound K (CK) from glycosylated protopanaxadiol ginsenosides. In order to improve the thermal stability of SS-BGL, molecular dynamics simulations were used to determine the residue-level binding energetics of ginsenoside Rd in the SS-BGL-Rd docked compl...
Continue readingThearubigins (TRs) are chemically ill-defined black tea pigments composed of numerous catechin oxidation products. TRs contain oligomeric components; however, the oligomerization mechanisms are poorly understood. The comparison of the 13C nuclear magnetic resonance (NMR) spectra of TRs with different molecular sizes suggested the participation of A-ring methine car...
Continue readingBovine lactoferrin (bLF) is widely known as an iron-binding glycoprotein from the transferrin family. The bLF molecule exhibits a broad spectrum of biological activity, including iron delivery, antimicrobial, antiviral, immunomodulatory, antioxidant, antitumor, and prebiotic functions, thereby making it one of the most valuable representatives for biomedical applic...
Continue readingLactic acid bacteria (LAB) were screened from Lutjanus russellii (red sea bass), and their antimicrobial activities were evaluated against two Aeromonas species isolated from the Nile tilapia, namely, Aeromonas veronii (AV) and Aeromonas jandaei (AJ). Three LAB isolates, Enterococcus faecium MU8 (EF_8), Enterococcus faecalis MU2 (EFL_2), and E. faecalis MU9 (EFL_9)...
