Extraction and Comprehensive Characterization of Starch From Ryegrass (Lolium multiflorum L.) Seeds as a Non‐Conventional Source

Starch - Stärke, Volume 78, Issue 1, January 2026.
A native starch was extracted from ryegrass (Lolium multiflorum L.), yielding a high‐purity product with a significant starch content. The starch exhibited type A and V crystallinity, with a mean particle size (D50) ~7 nm, high swelling power, and low retrogradation tendency.

Robust Synthesis of Prebiotic Precursors in Drying Reactions of Amino Acids and Keto Acids

ChemSystemsChem, Volume 8, Issue 1, January 2026.
Drying conditions drive reactions between amino acids and keto acids, generating a wide variety of small, reactive species, highlighting for the first time the potential significance of drying reactions in proto‐metabolism on early Earth. Condensation‐dehydration reactions are critical to both metabolism and polymerization in extant biology, and their ...

Templated Tube Growth About a Reactive Gas Plume: The Pharaoh's Serpent Reaction, Thermodecomposition of Mercury Thiocyanate in Air

ChemSystemsChem, Volume 8, Issue 1, January 2026.
XX XX ABSTRACT The pharaoh's serpent reaction, the thermodecomposition of mercury thiocyanate in air, is a classic chemical demonstration. We analyse and characterize the reaction products, composed of two different phases, graphitic carbon nitride, C3${\rm C} _3$N4${\rm N} _4$, and metacinnabar, HgS.

Effects of High Levels of Enzyme Blend With Probiotic on Performance, Intestinal Morphology, Microbial Population, and Immune Response in Broiler Chickens

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
High levels of enzyme blend (450 and 600 mg/kg) combined with probiotics improved growth performance and reduced coliform populations in broiler chickens, without affecting carcass traits, meat quality or immune response. These findings highlight the synergistic effects of enzymes and probiotics on gut health and productivity.2 ABSTRACT Background ...

Synergistic Effects of Garlic Extract and Mannan‐Oligosaccharide Prebiotic Supplementation on Growth Performance, Carcass Quality, Immunity, Gut Morphology and Microbiome in Broiler Chickens

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Garlic extract and mannan oligosaccharide (MOS) synergistically improved broiler growth, carcass weight, immune response, gut morphology and microbial balance, with half‐dose combination (Combo‐I) showing the most consistent benefits, offering a sustainable alternative to antibiotic growth promoters. ABSTRACT This study evaluated the effects of dietary

Water-Air Interfaces as Environments to Address the Water Paradox in Prebiotic Chemistry: A Physical Chemistry Perspective.

Journal of Physical Chemistry A, 2021
The asymmetric water-air interface provides a dynamic aqueous environment with properties that are often very different than bulk aqueous or gaseous phases and promotes reactions that are thermodynamically, kinetically, or otherwise unfavorable in bulk ...

Positively charged membranes for dye/salt separation based on a crossover combination of Mannich reaction and prebiotic chemistry.

Journal of Hazardous Materials, 2022
With the advent of increasingly loose nanofiltration membranes for dye desalination, synthesis methods based on interfacial polymerization and bio-inspired materials such as polydopamine (pDA) have been investigated. However, the long polymerization time

Prebiotic chemistry

Chemical Society Reviews, 2012
Without doubt, one of the most fascinating questions ever asked is ''What is life?'', immediately followed by ''How and where did life arise?''. Both questions are by no means exclusively related to chemistry and biology. Indeed, it was soon realized that concepts from astrophysics, geochemistry, geophysics, planetology, earth science, bioinformatics ...

Prebiotic chemistry: From dust to molecules and beyond

2022
Prebiotic chemistry has dominated the origins of life (OoL) field to such an extent that often these terms have been used interchangeably. While prebiotic chemistry has benefited from cross-seeding with other disciplines (e.g., biochemistry, biophysics, computational sciences, geosciences), the OoL problem is still primarily a chemical one.
