Figure 1. The structures of hemoglobin (L) and carboxyhemoglobin (R) differ only by the molecule bound to the iron atom (orange). In normal hemoglobin, iron binds oxygen (O₂), enabling its transport ...

This particle diagram represents water or, to use its chemical formula, H₂O which is a compound of the elements hydrogen and oxygen. In one molecule of water, there are two hydrogen atoms and ...

The structure of a vancomycin biosynthetic enzyme in complex with a substrate analog, and with molecular oxygen bound in its active site, supports the idea that cofactor-independent oxygenases act ...
