Curcumin has a wide range of application prospects, with various bioactivities in the food industry and in the biomedical field. However, curcumin has poor water solubility and is sensitive to pH, light and temperature. In this study, curcumin-chitooligosaccharide (CUR-COS) complexes were prepared via mechanochemical methods, and the CUR-COS complex was more soluble after freeze-drying (up to 862-fold greater than that of curcumin).

Cereal arabinoxylans (AX) are complex non-digestible polysaccharides and their molecular structural features significantly influence their degradation and metabolic behaviors within the body. This study focuses on investigating the impact of wheat AX hydrolysates produced by different glycoside hydrolases on the gut microbiota during colonic fermentation. Endo-1,4-β-xylanase (XYN) and arabinofuranosidase (ARF) were used to hydrolyze the xylan backbone and remove the arabinose side chains, respectively.

Fucosylated chondroitin sulfate (FCS) from Holothuria mexicana (FCS) was selected for investigation because of its intriguing branch features. Selective β-eliminative depolymerization and the bottom-up assembly were performed to unravel that FCS consisted of a {D-GlcA-β1,3-D-GalNAc} backbone and branches of alternating Fuc (55 %) and D-GalNAc-α1,2-L-Fuc (45 %), the highest proportion of disaccharide branch reported to date. In branches, sulfation could occur at every free -OH site except O-3 of GalNAc, being the most complex and various structure features of natural FCS.

The appetite of honeybees for food is crucial to their survival and reproduction, as they sustain their entire colony by collecting pollen and nectar for nutrients. Dopamine, an important neurotransmitter, regulates appetite and satiety. However, how dopamine regulates honeybee foraging behavior remains unexplored.

Prolactin induced-protein (PIP) has been found to be rich in immunomodulatory epitopes, including -acetyllactosamine (LacNAc) and ,-diacetyllactosamine (LacdiNAc) residues, which may constitute ligands for galecin-3 (Gal-3). In the current study, we aimed to investigate the reactivity of galactose- and -acetylgalactosamine-specific lectins with human seminal plasma PIP. Subsequently, we examined the direct interaction between seminal plasma PIP and galectin-3, and next analyzed whether there are any differences in the interaction associated with impaired semen parameters.
