Considering the state-of-the-art views of the geochemical conditions of the primitive earth, it
seems most likely that peptides were produced ahead of all other oligomer precursors of …

Addressing the emergence of life from a systems biology perspective, this new edition has
undergone extensive revision, reflecting changes in scientific understanding and evolution …

Conspectus In many origin-of-life scenarios, inorganic materials, such as FeS or mineral
clays, play an important role owing to their ability to concentrate and select small organic …

Oligomerization of a peptide was attempted in a flow reactor that simulated a submarine
hydrothermal system. When fluid containing glycine repeatedly circulated through the hot …

Peptide formation from amino acids is thermodynamically unfavorable but a recent study
provided evidence that the reaction occurs at the air/solution interfaces of aqueous …

We propose the nuclear geyser model to elucidate an optimal site to bear the first life. Our
model overcomes the difficulties that previously proposed models have encountered …

Catalytic efficiencies of clay (hectorite), silica and alumina were tested in peptide bond
formation reactions of glycine (Gly), alanine (Ala), proline (Pro), valine (Val) and leucine …

The present study examines the selective adsorption and polymerization of two amino acids,
glutamic acid (Glu) and arginine (Arg), on a cationic clay mineral, montmorillonite (Mt). Two …

Concentrating simple organic molecules, such as amino acids, in the adsorbed phase could
have been an early step in prebiotic evolution towards more complex bio-macromolecules …

The book provides insight into the working of clays and clay minerals in speeding up a
variety of organic reactions. Clay minerals are known to have a large propensity for taking …
