Diatomic molecules are when only two atoms combine. An example of adiatomic moleculeis carbon monoxide (CO) made of a single atom of carbon and one of oxygen. If the two atoms are the same element, it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Poly...
aThe oxygen atom of the water molecule is more electronegative than the hydrogen atom (i.e., it attracts more the electrons). As a result, the side of the molecule with the oxygen atom has a partial negative charge. A molecule with such a charge difference is called a dipole.[translate]...

Shown here is one of the four subunits of the hemoglobin molecule. A molecule of oxygen (O2) is shown bound to Fe. The Fe2+ ion is coordinated to 4 N's on the pyrrole ring, The 5th ligand is a proximal His (the 8th amino acid on helix F). Oxgen is shown bound to the 6th coo...

The formation of H2O2 due to phenolic oxidation is known to proceed in two steps: a polyphenol H2Q is oxidized to a semiquinone free radical HQ● in a reaction coupled to the reduction in molecular oxygen to the superoxide anion radical O2●− (1); then, semiquinone is oxidized to ...
Apart from searching for new structures of potential drugs, there is a second approach based on a combination of two or more well-known pharmacophores into one molecule with synergistic activities. Nasr et al. [13] described synthesis and antimicrobial effects of tiophene, acrylamide, aryl...
Pronounced complex V assembly defect by OPA1 KO with a functionally inconsequential reduction in mtDNA level suggests a potentially specific role of the OPA1 molecule in the assembly or stability of complex V. Despite the decreased level of mature complex V, OPA1-KO mitochondria exhibited an ...
