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 ...

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.

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.

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, 1973Questions 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

Current Opinion in Biotechnology, 2012
A wealth of information has been gathered over the past 15 years on prebiotics through experimental, animal and human studies, with the aim to understand the mechanism of actions and elucidate their beneficial health effects to the human host. Significant amount of evidence exists for their ability to increase the bioavailability of minerals and ...

Prebiotic photosynthetic reactions
Biosystems, 1981Historically, numerous attempts have been made to mimic - by means of inorganic model reactions - the photosynthetic fixation of CO2 by green plants. The literature in this field is strewn with claims and counter-claims. Two factors have led us to reexamine this subject: firstly; doubts concerning the highly reducing model for the atmosphere of the ...

Journal of Clinical Gastroenterology, 2004
The intestinal flora of breast-fed infants is an important physiologic factor in the function of the gut and in the development of the immune system. The current research is part of a group of studies performed to answer the question whether a bovine milk formula supplemented with a prebiotic mixture from galactooligosaccharides and ...
