[translate] aFor example, protein is a good source of iron, but because protein molecules are so big, plants can not use the iron contained in the protein. 例如,蛋白质是铁的一个好来源,但,因为蛋白质分子是很大的,植物不可能使用在蛋白质包含的铁。 [translate] ...

Inside, rubber and iron have their atoms (in the case of iron) and molecules (in the case of rubber) arranged in totally different ways. Iron has a regular or crystalline structure (like a climbing frame with atoms at the corners), while rubber is a polymer (made from long chains of ...
the solid, all of which is made up of molecules with the formula H2O. __4__ This is true of other chemical substances; most of them can exist as gases or as liquids or as solids. We may normally think of iron as a solid, but if we will heat it in a furnace, it will melt an...
H2O molecules are arranged around the axis of the erionite cavity pro- Natural fibrous erionite has recently gained great concern because its environmental exposure has been linked to the outbreak of malignant mesothelioma (MM) epidemics in several villages of Central Anatolia, Turkey12,13.

This is especially relevant in hypoxia, in which NO has been implicated as a key regulator of acute hypoxic vasodilatory responses1,2,3. A major source of hypoxic NO generation is the reaction of the nitrite anion (NO2–) with metal centers, especially the iron in erythrocytic hemoglobin2,4...
transport system for iron uptake from low-molecular-masscomplexes including ferric citrate was well documented [19–23].However,specific molecules involved in the transportsystem remain obscure in spite of the fact that the identificationof these molecules is highly challenging mainly due totheir ...
