Catalytic conversion of biomass-derived compounds to various amino acids: status and perspectives

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 7,   Pages 817-829 doi: 10.1007/s11705-022-2254-z

Abstract: Amino acids are important nitrogen-containing chemicals that have a variety of applications.Currently, fermentation is the widely employed method to produce amino acids; however, the products aremostly limited to natural amino acids in the L-configuration.Catalytic synthesis is an alternative approach for the synthesis of amino acids with different typesMaking full use of inherent nitrogen in biomass (i.e., chitin and protein) to produce amino acids avoids

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 4,   Pages 465-470 doi: 10.1007/s11705-014-1452-8

Abstract: The utilization of poly (2-hydroxyethylmethacrylate) grafted agar (Ag-g-P(HEMA)) as a matrix for the controlled release of 5-aminosalicylic acid was investigated. Grafted copolymers of 2-hydroxyethylmethacrylate (HEMA) monomers on agar were synthesized by microwave assisted method. drug release studies were performed at pH values of 2 and 7 in order to investigate the possibility of pH triggered release for colon targeted drug delivery. Further, the percent grafting . (the time taken for release of 50% of the enclosed drug) value was studied and the results indicate that it may be possible to develop a programmable drug release matrix based on grafted polysaccharide. Ag-g-P(HEMA) appears to be a useful matrix for controlled release.
