Carbons especially play a major role in the building stages of life. It's important due to its ability to form variety of chemical bonds compare to any other ones. Accesses to these chemicals are not hard to obtain. This is due to the nature of the geological processes that occur on large, rocky planets like Earth, Mars and Venus. These elements are readily available at the surface and interior of solid planets. It is in reason to said that life could exist on Mars and Venus, since these chemicals are the ingredients to begin life .
Organic molecule is another type of chemicals that is the significant inorder for life to work correctly. These organic molecules such as methane, ethane and specially amino acids combine with biogenic chemicals help to create more complicated molecules to form life. .
Amino acid is one of the more complex chemicals that is essential to life. If amino acid is presence in an environment, there is strong indication that life could exist in that area. Scientists at NASA had successfully created amino acids, in conditions that are similar in space. This suggested that amino acids in interstellar clouds may have caught on to the Earth in its early stages of formation. Furthermore, new stars and planets are forming in the same interstellar clouds that amino acids are being developed. Thus its increase the chances that life could evolve else where in the universe.
Cell's membrane is important in the functioning of living cells. Membranes are a vital component of all cellular life. It required for cell replication and membrane transport. By doing a simple experiment evidence had shown that cell membrane structures can form in space. Scientists have created primitive cells that are the same as membranous structures found in all living things when place in water. These chemical compounds may have played a part in the origin of life. Dr. Louis Allamandola said "This discovery implies that life could be everywhere in the universe".
