Antioxidants and Antidiabetic Potential of Polyphenolic Fractions and Crude Extracts of Rhus coriaria L. Fruit, Punica granatum L. Peel, and Terminalia catappa L. Leaves: In Vitro and In Vivo Evaluation

open access: yesChemistry &Biodiversity, EarlyView.
This graphical abstract represents the extraction, characterization, and biological evaluation of bioactive compounds derived from specific plant sources. The top section illustrates Rhus coriaria (sumac) fruit, Punica granatum (pomegranate) peel and Terminalia catappa (Indian almond) leaves', which are known for their rich phytochemical composition ...

Interactive effects of temperature and nitrogen source on the elemental stoichiometry of a polar diatom

open access: yesLimnology and Oceanography, Volume 67, Issue 12, Page 2750-2762, December 2022., 2022
Abstract A recent study hypothesized that the near‐zero temperatures that generally prevail in Arctic waters negate the influence that different nitrogen (N) sources can otherwise have on the growth and elemental stoichiometry of marine micro‐algae. Here we test this hypothesis experimentally by evaluating how temperature (0–9°C) affects the growth and

Purine Chemistry in the Early RNA World at the Origins of Life: From RNA and Nucleobases Lesions to Current Key Metabolic Routes

open access: yesChemBioChem, EarlyView.
In the nascent processes of the beginnings and evolution of life, nucleobases and especially purines, ribonucleos(t)ides and primitive RNAs have been continuously modified. A RNA‐peptide world and key metabolic pathways probably have emerged from the corresponding chemical modifications resulting from adenine deamination, purine alkylation and ...

Designing Enzymatic Reactivity with an Expanded Palette

open access: yesChemBioChem, EarlyView.
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...
