We tested the stability and reaction of several amino acids using hydrothermal system simulators: an autoclave and two kinds of flow reactors at 200–250 °C. This study generally showed that there is a variation in the individual amino acids survivability in the simulators. This is mainly attributed to the following factors; heat time, cold quenching exposure, metal ions and also silica. We observed that, in a rapid heating flow reactor, high aggregation and/or condensation of amino acids could… 

Survivability and condensation of amino acids in simulated submarine hydrothermal environments

We tested the stability and reaction of several amino acids using hydrothermal system simulators: an autoclave and two kinds of flow reactors at 200–250°C. This study generally showed that there is a


Peptide concentrations estimated by the Lowry method were significantly higher when the mixture was heated at 300°C than those at lower temperatures, despite having more than 80% of the initial amino acids decomposed, and it was revealed that the peptides measured here were only part of the bonds in the heated products.

Spontaneous Polymerization of Glycine under Hydrothermal Conditions

The findings suggest that pressure and mineral-water interface strongly favor the formation of linear peptides and the polymerization of glycine is highly favored under pressure and in the presence of magnetite.

Alteration and Stability of Complex Macromolecular Amino Acid Precursors in Hydrothermal Environments

The interstellar complex organic analog could maintain as amino acid precursors after being treated at high temperature and pressure, but the molecular structures were altered during heating to form organic compounds that are more stable and can survive in elevated hydrothermal conditions.

Geoelectrochemistry-driven alteration of amino acids to derivative organics in carbonaceous chondrite parent bodies

A long-standing question regarding carbonaceous chondrites (CCs) is how the CCs’ organics were sourced and converted before and after the accretion of their parent bodies. Growing evidence shows that

Submarine hydrothermal vent systems: the relevance of dynamic systems in chemical evolution and prebiotic chemistry experiments

Since their discovery, submarine hydrothermal vent systems have been pointed out as important places where chemical evolution on Earth could have occurred; and their role in the process has been

Development of hydrothermal and frictional experimental systems to simulate sub-seafloor water–rock–microbe interactions

Since the discovery in 1977 of deep-sea hydrothermal vents, they have been shown to host unique but diverse biological communities, despite the dark, barren ocean-floor settings in which they exist.

Prebiotic oligomerization and self-assembly of structurally diverse xenobiological monomers

The oligomerization of a structurally diverse set of prebiotically plausible xenobiological monomers, which can hydrolytically interconvert between cyclic and acyclic forms, alone or in the presence of glycine under moderate temperature drying conditions is explored.

Nucléotides à l'interface minéral-eau et réactivité des acides aminés en conditions hydrothermales dans le contexte des origines de la vie

Les decouvertes de traces de vie primitive, fossiles et biosignatures, suggerent que celle-ci serait apparue il y 4,3 a 3,7 milliards d’annees. Cette emergence est le resultat d’etapes menant des



Reaction of Amino Acids in a Supercritical Water-Flow Reactor Simulating Submarine Hydrothermal Systems

A novel supercritical water flow-reactor was constructed in order to simulate submarine hydrothermal systems. The temperature of fluid inside the reaction tube could be monitored with thermocouples,

The Role of Submarine Hydrothermal Systems in the Synthesis of Amino Acids

Although amino acids can be generated from simple likely environmentally available precursors under SHS conditions, the equilibrium at high temperatures characteristic of SHSs favors net amino acid degradation rather than synthesis, and that synthesis at lower temperatures may be more favorable.

Autocatalytic Synthesis of Oligoglycine in a Simulated Submarine Hydrothermal System

It is demonstrated that when the initial reactant is glycine, the flow reactor can synthesize both di- and tri-glycine and the initial buildup of the yields of both the oligopeptides was found to be exponential with the elapse of time.

Thermal stability of amino acids in biogenic sediments and aqueous solutions at seafloor hydrothermal temperatures

Siliceous ooze was reacted with NaCl solution at temperatures of 100-250°C to evaluate the effect of the mineralogical and chemical properties of host sediments on the thermal stability of amino

Stability of amino acids in simulated hydrothermal vent environments

Stability and reactions of amino acids in submarine hydrothermal vent environments were examined. The decomposition rate was much slower in high hydrogen fugacity environments like the submarine

Elongation of oligopeptides in a simulated submarine hydrothermal system.

Oligomerization of a peptide was attempted in a flow reactor that simulated a submarine hydrothermal system, suggesting that prebiotic monomers could have oligomerized in the vicinity of submarine hydroThermal vents on primitive Earth.

Encapsulation of the glycine monomers enhanced the oligomerization of peptides in all cases and phospholipid vesicles were found to be better suited to enhance synthetic reactions at lower temperatures.

Stability of Amino Acids and Related Compounds in Simulated Submarine Hydrothermal Systems

Submarine hydrothermal systems (SHSs) have been thought of as a suitable environment for the origin of life subsequent to the abiotic synthesis of organic molecules. However, it has been pointed ou...
