Christian Bohr. Discoverer of Homotropic and Heterotopic Allostery
ABSTRACT This essay recounts and revisits the scientific contributions of Christian Bohr, highlighting his pivotal role in discovering allostery about 120 years ago. Bohr's meticulous experimentation led to identifying two distinct forms of allostery: homotropic (single‐ligand) and heterotropic (multi‐ligand), the latter widely recognized as the Bohr ...

Abiogenesis: discussion on the origin and evolution of life [PDF]
openL’abiogenesi è il presunto processo attraverso il quale la vita si è generata spontaneamente sulla Terra partendo da materiale non vivente.

APR‐A, an aggregation‐prone oligopeptide, can convert into APR‐B through distinct mutational pathways—some exclusively forming insoluble amyloid‐like peptides, others yielding water‐soluble, non‐aggregating monomers. These orthogonal pathways in chemical evolution may have driven macromolecular assembly under prebiotic Earth conditions, potentially ...

Factoring Origin of Life Hypotheses into the Search for Life in the Solar System and Beyond
Two widely-cited alternative hypotheses propose geological localities and biochemical mechanisms for life’s origins. The first states that chemical energy available in submarine hydrothermal vents supported the formation of organic compounds and ...

Evaluation of antiobesogenic properties of fermented foods: In silico insights
Abstract Obesity prevalence has steadily increased over the past decades. Standard approaches, such as increased energy expenditure, lifestyle changes, a balanced diet, and the use of specific drugs, are the conventional strategies for preventing or treating the disease and its associated complications.

Step‐by‐Step Towards Biological Homochirality – from Prebiotic Randomness To Perfect Asymmetry
This review focuses on the theories related to the emergence of biological homochirality, from assembly of building blocks at the monomer level, to polymerization into functional homochiral biopolymers. Abstract The history of life's formation and the origin of its stereochemistry are nearly as multifaceted as the life itself.

Abiogenesis and the Second Law of Thermodynamics
Abiogenesis, life arising from non-living matter, is reconsidered. A historic account is given from Darwin to the present with special consideration of the incipient relationship between quantum theory and life processes.

Abiogenesis not required to explain the origin of volcanic-hydrothermal hydrocarbons [PDF]
Abiotic formation of n-alkane hydrocarbons has been postulated to occur within Earth's crust. Apparent evidence was primarily based on uncommon carbon and hydrogen isotope distribution patterns that set methane and its higher chain homologues apart from ...
