Summary
Life requires biopolymer folding and evolution, which depend on solvents. Researchers ranked 54 solvents, finding many compatible with biopolymer existence beyond water, some found in space.
Area of Science:
- Astrobiology
- Biochemistry
- Physical Chemistry
Background:
- Life's origin hinges on the spontaneous folding and molecular evolution of biopolymers.
- The chemical makeup of biopolymers and their surrounding solvent critically influence these processes.
- Understanding solvent limitations is key to exploring the potential for life beyond Earth.
Purpose of the Study:
- To investigate the compatibility of various solvents with biopolymer folding and evolution.
- To identify potential alternative biochemistries and extraterrestrial solvents conducive to life.
Main Methods:
- Utilized molecular information theory and energy landscape theory.
- Analyzed 54 diverse solvents, including water, alcohols, hydrocarbons, and halogenated/aromatic solvents.
- Assessed solvent properties relevant to biopolymer stability and dynamics.
Main Results:
- Identified numerous solvents, besides water, that support liquid-phase biopolymer folding and evolution.
- Developed a ranking system for solvent compatibility with biopolymer existence.
- Found potential extraterrestrial solvents present in molecular clouds and expected on exoplanets.
Conclusions:
- Solvent choice is a universal constraint for life's emergence.
- Many non-water solvents can support the fundamental processes of life.
- This research expands the scope for searching for life in the universe.

03:00Molecular Chaperones and Protein Folding
17.9K
The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.

01:25Protein Folding
8.0K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

50.4K
Noncovalent attractions are associations within and between molecules that influence the shape and structural stability of complexes. These interactions differ from covalent bonding in that they do not involve sharing of electrons.
Four types of noncovalent interactions are hydrogen bonds, van der Waals forces, ionic bonds, and hydrophobic interactions.
Hydrogen bonding results from the electrostatic attraction of a hydrogen atom covalently bonded to a strong-electronegative atom like oxygen,...

91.7K
Around 4 billion years ago, oceans began to condense on earth while volcanic eruptions released nitrogen, carbon dioxide, methane, ammonia, and hydrogen into the primordial atmosphere. However, organisms with the characteristics of life were not initially present on earth. Scientists have used experimentation to determine how organisms evolved that could grow, reproduce, and maintain an internal environment.
