RAMPELOTTO, Pabulo Henrique. The chemistry of life as we do not know it. Quím. Nova [online]. 2012, vol.35, n.8, pp.1619-1627. ISSN 0100-4042.

It has been widely suggested that life based on carbon and water is the only plausible biochemistry, and specifically that terrestrial biochemistry of nucleic acids, proteins, and sugars is likely to be universal. However, according to our current knowledge of physics and chemistry, this may be just a geocentric concept. In recent decades, laboratory experiments and theoretical studies have indicated that life could be based on molecular structures substantially different from those we know. In this work, these studies are discussed in order to improve our knowledge on the fundamental nature of life.

Keywords : life; astrobiology; geocentric concept.
