Prebiotic chemistry

Chemical Society Reviews, 2012
Without doubt, one of the most fascinating questions ever asked is ''What is life?'', immediately followed by ''How and where did life arise?''. Both questions are by no means exclusively related to chemistry and biology. Indeed, it was soon realized that concepts from astrophysics, geochemistry, geophysics, planetology, earth science, bioinformatics ...

prebiotic transamination

Origins of life and evolution of the biosphere, 1997
Biological amino acids and alpha keto acids directly condense with decarboxylation and transamination to yield product amino acids. This process is closely related to unusual amino acid decarboxylase enzymes in certain microorganisms and may represent a primordial mode of amino acid metabolism.

Prebiotics

2013
The human large intestine is an intensively colonized area containing bacteria that are health promoting as well as pathogenic. This has led to functional food developments that fortify the former at the expense of the latter. Probiotics have a long history of use in humans as live microbial feed additions.

Prebiotic Petroleum

Origins of Life and Evolution of Biospheres, 2014
This short communication summarizes a global and continuous reflection on the origins of life. "Prebiotic Petroleum" assumes that "the class of most complex molecules of life that may have geochemical and abiotic origin is the class of fatty acids with long aliphatic chains" and proposes a physical process for the formation of liposomes.

Prebiotic Activation Processes

Nature, 1973
Questions regarding the combination of amino acids and ribonucleotides to polypeptides and polynucleotides are investigated. Each of the reactions considered occurs in the solid state in plausible prebiotic conditions. Together they provide the basis for a unified scheme of amino acid and nucleotide activation. Urea, imidazole and Mg(++) are essential
