Glycans can regulate their own biosynthesis by modifying enzyme activity
Glycans are chains of sugars that attach to cells through proteins or lipids, changing their chemical characteristics. Glycans can be incredibly complex and branched in structure, contributing to the stability of the extracellular domain of cells and.....»»
Novel self-cleaning electrode developed for alkaline-earth metal peroxide synthesis
Metal peroxide (MO2, M=Ca, Sr, Ba) is an alternative to hydrogen peroxide (H2O2). It has excellent oxidative properties, superior chemical stability, high purity, and is easy to store and transport. It has been widely used in wastewater treatment and.....»»
New chemical treatment reduces number of plant pores that regulate water loss
Researchers from Nagoya University Institute of Transformative Biomolecules (WPI-ITbM) in Japan and their colleagues have identified and derivatized a chemical compound that effectively regulates the density of stomata in model plants. Stomata are cr.....»»
Chemical trick activates antibiotic directly at the pathogen
Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in about 30% of treated patients. A research team at the Helmholtz Cente.....»»
Key role of structural defects in amorphous solid deformation uncovered
Researchers at the Indian Institute of Science Education and Research (IISER) Pune and the CSIR-National Chemical Laboratory (NCL) Pune have shown that the macroscopic deformation of amorphous solids is controlled by structural defects within the mat.....»»
