Serial transfer can aid the evolution of autocatalytic setsAbstract
Background
The concept of an autocatalytic set of molecules has been posited theoretically and demonstrated empirically with catalytic RNA molecules. For this concept to have significance in a realistic origins-of-life scenario, it will be important to demonstrate the evolvability of suc... ...

Systems chemistry: using thermodynamically controlled networks to assess molecular similarityAbstract
Background
The assessment of molecular similarity is a key step in the drug discovery process that has thus far relied almost exclusively on computational approaches. We now report an experimental method for similarity assessment based on dynamic combinatorial chemistry.

Design and synthesis of nucleolipids as possible activated precursors for oligomer formation via intramolecular catalysis: stability study and supramolecular organization
Tập 5 - Trang 1-23 - 2014
Fatty acid vesicles are an important part of protocell models currently studied. As protocells can be considered as pre-biological precursors of cells, the models try to contribute to a better understanding of the (cellular) origin of life and emphasize on 2 major aspects: compartmentalization and replication. It has been demonstrated that lipid-based membranes are amenable to growth and division ......
Inferring chemical reaction patterns using rule composition in graph grammars
- 2013
Modeling molecules as undirected graphs and chemical reactions as graph rewriting operations is a natural and convenient approach to modeling chemistry. Graph grammar rules are most naturally employed to model elementary reactions like merging, splitting, and isomerisation of molecules. It is often convenient, in particular in the analysis of larger systems, to summarize several subsequent reactio......
The relationship between difference and ratio and a proposal: Equivalence of temperature and time, and the first spontaneous symmetry breaking
Tập 1 - Trang 1-7 - 2010
The mathematical form of the energy-entropy relationship is that of the relationship between the difference and the ratio of any two 'entities' x and y creating a geometrical 3D projection x = y·z, i.e., a surface of the shape of a hyperbolic paraboloid being a particular form of a quadric. The significance of this relationship is discussed here in a realm beyond thermodynamics. Somewhat intuitive......
Exploding vesicles
Tập 2 - Trang 1-6 - 2011
While studying fatty acid vesicles as model primitive cell membranes, we encountered a dramatic phenomenon in which light triggers the sudden rupture of micron-scale dye-containing vesicles, resulting in rapid release of vesicle contents. We show that such vesicle explosions are caused by an increase in internal osmotic pressure mediated by the oxidation of the internal buffer by reactive oxygen s......
Organoautocatalysis: Challenges for experiment and theory
Tập 1 - Trang 1-7 - 2010
Recent reports about enantioselective organoautocatalytic systems, in which small organic molecules assist in their own formation and under conservation of their absolute configuration, are discussed. This process, appearing as a natural extension to non-covalent enantioselective organocatalysis, seems analogous to template-directed self-replication, previously observed in simple organic molecules......
Pathway control in the self-construction of complex precipitation forms in a Cu(II)-oxalate system
Tập 3 - Trang 1-6 - 2012
Many biological systems contain complex precipitation patterns. These structures are considered to be the result of finely tuned and genetically encoded developmental pathways. The amount of encoded information needed to generate and manipulate these structures is poorly understood. Investigating the dynamics of spontaneous pattern formation in non-biological systems provides insights to the physi......
