aNitrate is also a small molecule, NO3, and it is also absorbed into the root. Other nutrients such as phosphorous, potassium, iron, magnesium etc are all small enough to enter the roots 硝酸盐也是一个小分子, NO3,并且它也被吸收入根。 其他营养素例如亚磷,钾、铁,镁等是全部足够小的进入根...

Many studies from independent laboratories have implicated erythrocyte NO generation and/or delivery as a critical source of hypoxic vasodilation, although questions remain about the nature and stability of the molecule carrying “NO bioactivity”5,6,7,8. Other sources of NO for hypoxia-driven ...
Our simulations used a solvent molecule to coordinate the bound metal, but it is possible that the conserved aromatic residue at position 893 indirectly participates in coordination of the metal (13). For example, the π-ring system of Tyr-893 could coordinate a solvent molecule that participates...

AlphaFold-predicted structure of theRuminococcus gnavusBilR with sequences coloured to show their degree of conservation within clade 1 based on a ConSurf conservation analysis. A docked bilirubin (green) and FMN (orange) molecule are shown on the structure, and the insets show the potential site...

In many cases the components of a mixture can be separated quite easily, e.g. using a magnet to separate iron filings from a mixture of iron filings (dark grey colour) and sulphur (yellow colour). Note: This is one of a series of simple pages introducing key concepts in introductory che...
