Investigation on Catalyst Selection for Polymerization Processes in Petrochemical Industries
Abstract: Organic polymers are long-chain compounds made of several repeating units. These polymers are either natural, such as protein, cellulose, starch or synthetic, such as polyethylene (a plastic), polyesters and polyamides (plastics and fibers) and polybutadiene (rubber).Many organic compounds possessing multiple bonds have the tendency to polymerize in the presence of an initiator. Polymerization of these compounds can either be affected by the use of chemical initiators such as free radicals …

Cryogenic Electron Microscopy Reveals Conformational Dynamics and Catalytic Mechanisms of Human Fatty Acid Synthase in De Novo Lipid Biosynthesis
Abstract: Fatty acid synthase (FASN) is a multifunctional homodimeric enzyme central to de novo fatty acid synthesis in mammals. Recent cryogenic electron microscopy (cryo-EM) studies have illuminated the structural basis of FASN catalysis, revealing multiple conformational states throughout the synthesis cycle. These findings show that the acyl carrier protein (ACP) domain dynamically shuttles substrates between spatially separated active sites, while the condensing and modifying regions remain structurally stable. In contrast to …
