Significados de oxygen atom em inglês

Alteration of the oxygen atom of the semicarbazones by isosteres did not enhance anticonvulsant properties.

Thinking of Water as Particles Yes, water is actually two hydrogen atoms with an oxygen atom.

We are composed mostly of water-moleculesconsisting of an oxygen atom bound to two hydrogen atoms.

Water, of course, is made up of H 2 O -two hydrogen atoms, and one oxygen atom.

Clearly, then, the oxygen atom, like a creature with two hands, is able to clutch two other atoms.

There are two hydrogen atoms bonded to one oxygen atom-butthe hydrogen atoms have a 108-degreeangle between them.

In the liquid form, the hydrogen atoms of one water molecule are attracted to the oxygen atom of another molecule.

The powerful electron cycling capability of iridium and the cooperative iridium-aluminum interplay are emphasized to drive the oxygen atom-transfer behavior.

The substrate-binding site is formed by an opening above the heme that enables organic substrates to approach the activated oxoferryl oxygen atom.

The reaction is proposed to occur through two hydrogen shifts from the nitrogen to the oxygen atom giving rise to multicentered transition states.

Water molecules have a more V-shaped geometry, with an oxygen atom at the vertex bonded with two hydrogen atoms, protruding like a rabbit-ear antenna.

In vitro (18)O(2) experiments establish that the oxygen atom incorporated into the substrate is derived from molecular oxygen.

The oxygen atom, being divalent, is capable of uniting itself to two other atoms of oxygen or other elements, and thus with oxygen forming ozone.

In this model the oxygen atom of the sulfonamide make hydrogen bond interactions with the catalytic residues Ser170 and Ala172.

Because the oxygen atom exerts a stronger pull on the electrons (small dots) it shares with the hydrogen atoms, the water molecule is electrically unsymmetrical.

For example, oxygen atoms can glow green or red, depending on their altitude.
