Formation of the star, prebiotic of organic molecule complex based on carbon. Dissemination 82nd
It is considered that with the formation of the elements of the periodic system, from the simple hydrogen atom described in Disclosure 77 of Veterinaria Digital, during the evolutionary processes and explosives of the stars also form the complex of the molecules based on oxygen, nitrogen and hydrogen. These compounds are released into space and accumulate in protoplanetary disks around new stars, future newly forming planets. Thus primitive oceans and atmospheres of the planets contain varying amounts of hydrogen cyanide (HCN), and its derivative methyl cyanide (CH3CN), ammonia (NH3) and methane (CH4).
These molecules have been found in chemical fossils on the Earth, in comets fallen on Earth, asteroids of Kuiper Belt (beyond Neptune) and in formations beyond our solar system (planetary disk of the star MWC 480, 455 years, sunlight in the constellation Taurus).
Methyl cyanide, hydrogen cyanide, ammonia and methane are considered precursors of amino acids, basic elements for the formation of proteins, because it contains carbon and nitrogen. So methionine can be synthesized in terrestrial conditions from propylene, methyl thiol, methane and ammonia; Hill is obtained by the reaction of methanol and ammonia which produces the trimethylamine to react with ethylene oxide. Stanley Miller proposed a process of mixing distilled water with ammonia gas, methane and hydrogen and electric shocks until 60,000 volts to this mixture for 3 days experiment. By analyzing the final solution, Miller detected the presence of acetic acid, ADP-glucose, and the amino acids glycine, alanine, glutamic acid and aspartic acid that had formed under conditions similar to those of early Earth components. Sean atmospheric or surface formation of amino acids accumulated in the shallow water by increasing their concentration.
Sidney Fox later showed spontaneous formation of proteins from amino acids. His early work showed that under similar conditions to those of early Earth, amino acids could spontaneously form small peptides and subsequent work revealed that these amino acids and small peptides can form spherical membranes, called microspheres or microspheres. Fox defined these formations as protocells, protein spheres that can grow and reproduce, as an intermediate step in the origin of life.
Finally we return to the ideas proposed by Alexander Oparin consisting of proteins dissolved in water, form colloids grouped by electrostatic forces resulted protobionts coacervates that could coexist with other enzymatic proteins and polysaccharides in solution and even included therein.
This sequence of events takes us from the formation of the basic chemical elements in the formation of chemical compounds essential for life, but does not allow us to advance to the origin of life.
