Two hypotheses about the source of organic molecules on Earth would be, first, that they formed out of the original chemical composition of the planet, because of the energy provided by solar radiation and lightning, and second, that they were already present in interstellar dust clouds and therefore were part of the original composition of the Earth when it condensed out of an interstellar dust cloud.
Carbon and Nitrogen were most likely the the first two possible sources of simple organic compounds on earth as a result of exploding stars.
O2
An Organic Molecule was made of common elements, like Carbon, Hydrogen and Oxygen. These molecules were washed into sea to form pools of Organic Matter. As timed passed these molecules formed long and complex molecule chains. Slowly these molecule made themselves more advanced in different functions of their body from reproduction. They kept reproducing mutating complex molecules until these molecules developed into the first cells. These cells developed into the first cells without nucleus. Cells without nucleus are now considered to be the first types of microorganisms. So people could say that a organic molecule is the the 'reign' of Microorganisms.
could be inorganic or organic
Organisms are composed of organic, that is carbon containing molecules. Glucose (C6H12O6) and adenosine triphosphate (ATP), carbon dioxide (CO2), and DNA/RNA macromolecules are such organics.
The vital force theory was a theory presented by Berzelius. The 1809 theory stated that organic compounds could not be synthesized in a laboratory. The German Scientist contradicted the theory, and prepared Urea through Ammonium Chloride and Potassium Cyanate so eventually is was discarded.
it's between A. amino acids or B. monosaccharides C.fatty acids or D.phospholipids
In the atmosphere, in the upper layers of waters, basically everywhere where there's enough of the component elements, energy and convection available.Note that recent observations in astronomy have shown massive amounts of organic molecules to be present about newly formed star systems, so it's very well possible that some organic molecules were transported to Earth by comets, etc.
When the field of organic chemistry was just beginning, it was widely believed that such chemicals were special in some sort of semi-supernatural sense and that only living things could make them due to a semi-supernatural ability they had that could never be duplicated naturally by man in the lab.This was gradually shown to be false as one after another of the organic chemicals were synthesized in the lab. Now we can even synthesize chemicals as complex as DNA in the lab (although once synthesized we often use living bacteria to mass produce it for us to reduce the costs).However the term organic chemistry stuck. There is now a new term biochemistry relating specifically to the chemistry of living things.
natural selection favored RNA molecules that synthesized catalytic proteins
Aleksander Oparin
because it was once believed that such compounds could not be synthesized in a lab but could only be produced in living things/organisms because of some "supernatural essence" unique to themorganic compounds are very complex carbon compounds
firstly small organic molecules formed from simple molecules.secondly these small molecules joined together into proteins and nucleic acids.thirdly molecules that could copy themselves such as RNA provided a way for molecular information to be inherited.fourthly,various organic molecules such as RNA and polypeptides formed "pre cells"
Stanley Miller conducted experiments that showed that simple organic molecules can form from an inorganic 'soup'. These experiments show that organic molecules could have formed from the inorganic componets of the earth early in its history.
There is no such molecule that is the basis of all structures. What I think you may mean is what atoms are the basis of organic molecules. In order for a compound to be considered organic, you have to have Carbon - Hydrogen bond/s. Organic molecules make up a considerable percentage of all living things. Some could argue that Deoxyribose nucleic acid may be.
Organic chemistry is the study of [covalently bonded] carbon containing molecules. It's actually distinct from biochemistry, but they have many overlaps, as most, if not all biological molecules contain carbon. In this sense, it could be called "the chemistry of life"
There are many places where one can purchase certified organic cosmetics. One can purchase certified organic cosmetics from popular on the web sources such as DrVita and ASOS.
