The prebiotic molecules observed in the interstellar gas.
Over 130 molecules have been identified in the interstellar gas and circumstellar shells, the largest among them is a carbon chain with 13 atoms and molecular weight of 147 (twice that of the simplest amino acid glycine). The high reliability of astronomical identifications, as well as the fairly accurate quantitative analysis which can often be achieved, is emphasized. Glycine itself has been ...
متن کاملEncapsulate Context
A system contains data that must be generally available to divergent parts of the system but we wish to avoid using long parameter lists to functions or global data. Therefore, we place the necessary data in a Context Object and pass this object from function to function. Audience Encapsulated Context is principally written for software developers designing and writing programs. The pattern was...
متن کاملSelection of Prebiotic Molecules in Amphiphilic Environments
A basic problem in all postulated pathways of prebiotic chemistry is the low concentration which generally is expected for interesting reactants in fluid environments. Even though compounds, like nucleobases, sugars or peptides, principally may form spontaneously under environmental conditions, they will always be rapidly diluted in an aqueous environment. In addition, any such reaction leads t...
متن کاملPrebiotic molecules in interstellar space: rotational spectroscopy and quantum chemistry
One of the most important open issues in astrochemistry and astrobiology is the detection in space of complex organic molecules, in particular those having a strong prebiotic role (i.e., related to the formation of biomolecule building blocks), and the identification of the chemical routes for their production. By means of selected examples, the role of rotational spectroscopy and quantum chemi...
متن کاملSynthesis and Characterization of Informational Molecules Formed under Prebiotic Conditions
All processes in extant biology are possible and facilitated by information encoded in polymers. Therefore, the origin of informational molecules had to be a crucial step in the origin of life on Earth. An important molecule in this context is RNA and the RNA World has been hypothesized as a crucial step in the transition from chemistry to biology. However, the RNA molecule is comprised of intr...
