Plant Based Polyphenol Associations with Protein: A Prospective Review

open access: yesBioResources, 2022
This review discusses the classes of plant polyphenols along with their binding mechanisms with protein molecules. Generally, polyphenols bind in covalent and non-covalent orientations with protein molecules. Their addition to the protein usually results

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

open access: yesFEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Understanding the Gastrointestinal Protective Effects of Polyphenols using Foodomics-Based Approaches

open access: yesFrontiers in Immunology, 2021
Plant polyphenols are rich sources of natural anti-oxidants and prebiotics. After ingestion, most polyphenols are absorbed in the intestine and interact with the gut microbiota and modulated metabolites produced by bacterial fermentation, such as short ...

Plant polyphenols in prevention of heart disease

open access: yesBratislava Medical Journal, 2012
Polyphenols (PPH) are a group of chemical substances found in plants, characterized by the presence of more than one phenol unit . The largest and best studied polyphenols are the flavonoids, which include several thousand compounds. PPH are the most abundant antioxidants in human diets.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
