The role of H2O in development and evolution

Water (H ₂ O) is a liquid that has nothing to discuss. But when studying at the molecular scale. The new simulation shows that the water molecules actually form two different types of structures that the separation and recombination take place as fast as lightning. This helps explain why it is easy to extract water from the wet environment.

Let's look at a simple water molecule, consisting of two hydrogen atoms linked to an oxygen atom. It is this water molecule that creates weak bonds with the water molecules around it and forms a more complex structure. This explains why water acts as a vehicle for the development and evolution of the most complex structurally shaped molecules in the universe including enzymes (enzymes are the protein molecules that play the role. The catalytic game speeds up chemical reactions.) Protein and DNA (DNA can be understood simply as a place to store all the information needed to create the life characteristics of each birth). object).

The question for scientists for more than a century and five years ago is considered by scientists to be one of the 125 most important issues that science has not yet explained: Why is it water? must be another liquid that acts as a vehicle for the development and evolution of the most complex structural morphology molecules in the universe?

New research may have discovered essential clues.

Researchers use specialized computers to learn how to form water bonds, a phenomenon that cannot be verified with the naked eye. Working with dedicated desktop computers, the team explored the configuration of water at the smallest levels through the use of models designed to study complex systems like the Internet, the spread. of viruses and folds of proteins.

Researchers have recorded the results and reports online in The Journal of Physical Chemistry B ,

Water molecules are intertwined and dynamically complex. Any volume of water contains two different types of molecular structures: the first is arranged in a tight structure, like a lattice, while the second type is an arbitrary, loose structure. sneaky like accumulating. But in the very small fraction of a second, both structures tend to split and recombine frequently. The result is a messy mix of water molecules. In the mixing loop, hydrogen atoms form connections that act as hooks, linked to carbon atoms or nitrogen predicted to establish the beginning of complex organic molecules. And this process has a much more significant effect on the creation of complex biological systems, such as proteins. Until now, scientists have concluded that no other liquid has excellent properties to replace water.

According to Zurich's University of Switzerland's Peter Hamm, " water is not just a solvent but water is an essential part of the protein structure ."

According to James Skinner, the physical chemist of the University of Wisconsin, Madison, USA. The results of this study help explain small but important details about the molecular motion of water.

Boston University physicist H. Eugene Stanley said " we will never understand biology until we understand water. "
