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 ...

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 Carbohydrates for Therapeutics
Endocrine, Metabolic & Immune Disorders - Drug Targets, 2021The food industry is constantly shifting focus based on prebiotics as health-promoting substrates rather than just food supplements. A prebiotic is “a selectively fermented ingredient that allows specific changes, both in the composition and/or activity in the gastrointestinal microflora that confers benefits upon host well-being and health ...

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 Prebiotic Synthesis of Oligonucleotides
Origins of Life, 1974This paper is primarily a review of recent developments in the abiotic synthesis of nucleotides, short chain oligonucleotides, and their mode of replication in solution. It also presents preliminary results from this laboratory on the prebiotic synthesis of thymidine oligodeoxynucleotides.

Recent advancements in food science have resulted in the extraction and synthesis of novel dietary fibers or prebiotics. Subsequently, great interest has emerged in developing strategies to improve metabolic conditions like osteoporosis by modulating the intestinal microbiome with fiber.

Origins of life and evolution of the biosphere, 2002
Cyanoacetylene is an earlier intermediate in a proposed prebiotic synthesis of cytosine, while cyanoacetaldehyde is a later intermediate. There is no scientific basis for the claim that cyanoacetaldehyde is more plausibly prebiotic than cyanoacetylene in this context.

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 ...

Prebiotic Synthesis of Nucleotides
Origins of life and evolution of the biosphere, 2001If an RNA-only world preceded more complex forms of life, then it is essential that the process whereby the first nucleotides were made be considered. Presumably there were no enzymes and no templates to facilitate the synthesis of the first nucleotides so another form of chemical evolution must have been involved. Answers to problems of this sort were
