Sentences with phrase «reactive molecules formed»

Not exact matches

Because the carbon atoms in a C36 fullerene must strain to form a sphere, the bonds between atoms are brittle; thus, the molecule is very reactive and quickly decomposes in air.

Volcanic plumes were ideal crucibles for sparking stable nitrogen to form reactive compounds that led to the first organic molecules, chemists report in the 15 August Geophysical Research Letters.

They found that soluble iron in the earliest oceans quickly combined with oxygen to form rust — forming reactive oxygen molecules, which damage biological tissue and make the cyananobacteria grow more slowly and produce less oxygen.

«Hyper - reactive molecules like radialenes form more stable substances very quickly.

That light is absorbed by the chlorine - based molecules, which then excite nearby oxygen molecules, creating a highly reactive form of oxygen, known as singlet oxygen, that rips apart nearby biomolecules and kills the tumor cell.

Ultraviolet radiation spices things up as well: It heats the grains and breaks up some of the molecules into reactive fragments, which in turn bond with other fragments to form new kinds of molecules.

But organisms from humans to algae also have another clock that doesn't rely on rhythmic gene expression to keep time, but instead uses the rise and fall of the reactive oxygen molecules that are formed as natural byproducts of metabolism.
