Evaluation of AOAC‐Method 2017.16: Detection of Oligosaccharides as Low Molecular Weight Soluble Dietary Fiber

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives In many countries, the Codex Alimentarius definition of dietary fiber has been adopted with the optional inclusion of oligosaccharides with a degree of polymerization (dp) of ≥ 3. These oligosaccharides are usually captured as low molecular weight soluble dietary fiber (LMWSDF). The suitability of the AOAC‐method 2017.

Chemical Evolution of Early Macromolecules: From Prebiotic Oligopeptides to Self‐Organizing Biosystems via Amyloid Formation

Chemistry – A European Journal, Accepted Article.
Short amyloidogenic oligopeptides (APRs) are proposed as early macromolecules capable of forming solvent‐separated nanosystems under prebiotic conditions. This study provides experimental evidence that APRs, such as the aggregation‐prone oligopeptide A (APR‐A), can undergo mutational transitions to form distinct variants, and convert to APR‐B, either ...

Thermodynamics of prebiotic synthesis [PDF]

arXiv
In this paper, I outline the correspondence of vector partitions with the combinatorics of dynamical systems whose states are partitions of multisets. I use the notion of a limiting shape of vector partitions to determine properties of the equilibrium distribution for these systems.

Light‐responsive mononucleotide coacervates

Chemistry – A European Journal, Accepted Article.
Liquid‐liquid phase separation (LLPS) is central to the formation of biomolecular condensates in modern cells and is also explored as a mechanism for assembling protocells. Phase‐separated droplets provide dynamic micro‐environments that concentrate reactants, enhance reactions, and allow molecular exchange, essential for both cellular regulation and ...

Grape Stalks Valorization towards Circular Economy: A Cascade Biorefinery Strategy

ChemSusChem, EarlyView.
A cascade protocol for grape stalks valorization has been proposed, characterized by a multidisciplinary strategy using unconventional techniques and subcritical water as a green solvent, where physical/chemical treatments synergistically interact with biological treatments to obtain added value products from all the biomass components.

Identification of carbohydrate gene clusters obtained from in vitro fermentations as predictive biomarkers of prebiotic responses

BMC Microbiology
Background Prebiotic fibers are non-digestible substrates that modulate the gut microbiome by promoting expansion of microbes having the genetic and physiological potential to utilize those molecules.

Exploratory analysis on the association of dietary live microbe and non-dietary prebiotic/probiotic intake with serum cotinine levels in the general adult population

Frontiers in Nutrition
BackgroundPrevious research has indicated the potential involvement of the microbiota in smoking-related processes. The present study seeks to examine the relationship between dietary live microbes, as well as probiotic or prebiotic consumption, and ...

Nonenzymatic Carboxylate Phosphorylation in Water

European Journal of Organic Chemistry, EarlyView.
The phosphorylation of carboxylic acids to acyl phosphates is a recurring reaction in the core of microbial metabolism, a set of processes thought to date back to the origins of life. This study shows that carboxylate phosphorylation occurs in water without enzymes or adenosine triphosphate (ATP), enabled by diamidophosphate and nitrite.
