AI Article Synopsis

  • - Hydrophobic vitamin B(12) was attached to a platinum electrode, enabling it to serve as a catalyst.
  • - This setup demonstrated a redox couple between Co(ii) and Co(i), meaning it can switch between two states.
  • - Under visible light, the Co(i) reacts with phenethyl bromide, successfully producing styrene with an impressive turnover number over 6000 in just 1 hour.

Article Abstract

Hydrophobic vitamin B(12) was covalently immobilized onto a platinum electrode surface, and the immobilized complex exhibits Co(ii)/Co(i) redox couple and in situ the Co(i) species reacts with phenethyl bromide to form styrene under irradiation with visible light with a turnover number of over 6000 for 1 h.

Nanoscale self-assembly and water retention properties of silk fibroin-riboflavin hydrogel.

J Chem Phys

January 2025

Department of Systems and Computational Biology, School of Life Sciences, University of Hyderabad, Prof. C. R. Rao Road, Gachibowli, Hyderabad 500046, Telangana, India.

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.

  • This study investigates using raw Greek honey in cacao-based materials for 3D printing, focusing on their physical properties and thermal stability.
  • It finds that incorporating honey not only improves the nutritional value and taste but also enhances the delivery of Vitamin D3, which is known to support the immune system but is difficult to absorb.
  • The research suggests that a 10% concentration of Lavender Honey is optimal for creating a stable and effective 3D-printed product, indicating the potential for these formulations in personalized health supplements and medicine.

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.

Molecular Basis for Cγ-N Bond Formation by PLP-Dependent Enzyme LolC.

Biochemistry

December 2024

Department of Molecular, Cellular, and Developmental Biology, University of California, Santa Barbara, Santa Barbara, California 93106, United States.

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.
