金属与酸反应的常用规律(The common law of the reaction between metal and acid) The common law of the reaction between metal and acid 1. the reaction of metals with acids is a redox reaction, and the amount of metal that loses electrons is equal to the amount of material that acids yield...
Iron is critical for host–pathogen interactions. While pathogens seek to scavenge iron to spread, the host aims at decreasing iron availability to reduce pathogen virulence. Thus, iron sensing and homeostasis are of particular importance to prevent host

Our synthesis of dn-iso-OPDA (5) is summarized in Scheme 5. Allylation of 1,3-cyclopentanedione 24 followed by methylation of the resulting 27 gave cyclopentenone 28. After the Grignard reaction of 28, dilution of the reaction mixture with hydrochloric acid promoted hydrolysis of the enol ether...
Members of the ZIP family function primarily in the influx of transition metal ions zinc and iron, into cytoplasm from extracellular space or intracellular organelles. The molecular determinants defining metal ion selectivity among ZIP family members remain unclear. Specifically, we reported before that ...
