AbstractBulk gold is chemically inert and is generally regarded as a poor catalyst. However, when gold is in very small particles with diameters
below 10 nm and is deposited on metal oxides or activated carbon, it becomes surprisingly active, especially at low temperatures, for
many reactions such as CO oxidation and propylene epoxidation. The catalytic performan...... hiện toàn bộ
AbstractStudies on ciguatera fish poisoning led to clarification of the absolute stereochemistry of ciguatoxin, gambierol, gambieric acids, and maitotoxin. Anisotropic NMR reagents and fluorometric chiral HPLC reagents were effectively used together with synthesis of partial structures. Structures of 16 ciguatoxin congeners were successfully elucidated by FAB/MS/MS...... hiện toàn bộ

AbstractThe pyridoxal‐5′‐phosphate (vitamin B6)‐dependent enzymes that act on amino acid substrates have multiple evolutionary origins. Thus, the common mechanistic features of B6 enzymes are not accidental historical traits but reflect evolutionary or chemical necessities. The B6 enzymes belong to four...... hiện toàn bộ
