Silk-fibroin hydrogels have gained considerable attention in recent years for their versatile biomedical applications. The physical properties of a complex hydrogel, comprising silk fibroin and riboflavin, surpass those of the silk fibroin-hydrogel without additives. This study investigates silk fibroin-riboflavin (silk-RIB) hydrogel at the atomistic level to uncover molecular structures and chemical characteristics specific to silk fibroin and riboflavin molecules in an aqueous medium.

Silica-based monoliths offer higher separation efficiency per unit pressure drop compared to particle-packed columns. Their application is limited by the commercial availability of different column chemistries. Pentafluorophenyl ligands enable hydrogen bonding, dipole-dipole, π-π, and hydrophobic interactions, facilitating the separation of various compounds.

This study investigated the release mechanism and digestive characteristics of soy protein isolate (SPI)-loaded vitamin B during digestion. According to the molecular docking results, vitamin B interacted with the SPI through a hydrophobic pocket on the SPI surface. Spectroscopy revealed that the fluorescence intensity of the SPI and complex system increased with the digestion time.

Pyridoxal 5'-phosphate (PLP)-dependent enzymes catalyze a diverse array of biochemical transformations, making them invaluable biocatalytic tools for the synthesis of complex bioactive compounds. Here, we report the biochemical characterization of LolC, a PLP-dependent γ-synthase involved in the biosynthesis of loline alkaloids. LolC catalyzes the formation of a Cγ-N bond between -acetyl--homoserine (OAH) and l-proline, generating a diamino diacid intermediate.
