What is the structure that has a molecular formula of \text{C}_8\text{H}_{14}\text{O}_2 and has an IHD of 2 ? What is the name of the compound with the formula SO3 ? What is the name of the compound with the formula Mg(No2)2 ? What is the name of the compound with a...
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...

There's no clear consensus on whether ionic compounds are molecular-based. Some sources consider them to have an underlying molecular structure, in which case, all compounds are molecular structures. Other sources treat the ionic compound as more of alattice networkthan a series of molecules, diff...
aCarbohydrates and their derivatives with high molecular compound concepts are called polysaccharides. Polysaccharide is not a purely a matter of chemistry, it is composed of different degree of polymerization material. 碳水化合物和他们的衍生物以高分子复合概念称多聚糖。 多聚糖不纯粹是事情化学,它由另外...
Using a traditional phenol oxidase assay, we saw no significant difference in PO activity between unsaturated and saturated samples (Fig. 1b(i) and Supplementary Data 1). However, from the metatranscriptome data, we detected significantly less PO gene expression in saturated samples than in ...
