Water and glycerol permeation through human AQP3 are described by exploiting advanced metadynamics approaches, which enabled both to explore the free energies involved in pore permeation and to achieve a description of the mechanisms with an atomistic level of detail.

This study evaluates the efficiency of 20 Natural Deep Eutectic Solvents (NADES) formulations for extracting curcuminoids and other bioactive compounds from turmeric and emphasize their ability to preserve and enhance antioxidant, antimicrobial, antidiabetic, and skin depigmentation effects. The NADES formulations, prepared using choline chloride (ChCl) combined with sugars, carboxylic acids, glycerol, amino acids, urea, polyols, and betaine, were assessed for their extraction efficiency based on the total phenolic content and curcumin concentration. Fourier transform infrared spectroscopy was employed to characterize the synthesized NADES and confirm their chemical composition.

The interaction of sodium phytate hydrate CHOP·xNa·yHO (phytNa) with Cu(OAc)·HO and 1,10-phenanthroline (phen) led to the anionic tetranuclear complex [Cu(HO)(phen)(phyt)]·2Na·2NH·32HO (), the structure of the latter was determined by X-ray diffraction analysis. The phytate is completely deprotonated; six phosphate fragments (with atoms P1-P6) are characterized by different spatial arrangements relative to the cyclohexane ring (1a5e conformation), which determines two different types of coordination to the complexing agents-P1 and P3, P4, and P6 have monodentate, while P2 and P5 are bidentately bound to Cu cations. The molecular structure of the anion complex is stabilized by a set of strong intramolecular hydrogen bonds involving coordinated water molecules.

Melatonin is involved in various functions such as the timing of circadian rhythms, energy metabolism, and body mass gain in experimental animals. However, its effects on adipose tissue lipid metabolism are still unclear. This study analyzes the effects of melatonin on the relative gene expression of lipolytic proteins in rat mesenteric adipose tissue and free fatty acid (FFA) and glycerol plasma levels of male Wistar rats fed a high-fat (HFD) or maintenance diet.

The water channel AQP3 is an aquaglyceroporin expressed in villus epithelial cells, and it plays a role in water transport across human colonic surface cells. Beyond water, AQP3 can mediate glycerol and HO transport. Abnormal expression and function of AQP3 have been found in various diseases often characterized by altered cell growth and proliferation.
