ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Spectrophotometric Determination of Gallotannins in Beer

Journal of AOAC INTERNATIONAL, 1973
Abstract A method for the determination of traces of gallotannins in beer, in the presence of other natural tannins, has been developed. The procedure is based on the formation of a deep blue iron-tannin complex which is evaluated spectrophotometrically at 530 nm.

Drivers of plant phenolic concentration across global drylands

Journal of Ecology, Volume 114, Issue 1, January 2026.
This study advances the understanding of how biotic and abiotic stressors shape plant defence strategies in global drylands. The findings shed novel insights about how plant secondary metabolites and their associated functions shift in response to changes in climate and grazing pressure, two key global change drivers with significant implications for ...

From MS1 to Structure: A Van Krevelen–DBE–Aromaticity‐Based Framework for Annotating Specialized Metabolites via High‐Resolution Mass Spectrometry

Rapid Communications in Mass Spectrometry, Volume 39, Issue 24, 30 December 2025.
ABSTRACT Rationale Classifying specialized metabolites in untargeted metabolomics remains a major challenge, particularly when relying solely on high‐resolution mass spectrometry (HRMS) data at the MS1 level. Traditional approaches using Van Krevelen diagrams often lack sufficient resolution to distinguish structurally similar metabolite classes ...

Gallotannin attenuates 2‑deoxy‑D‑glucose‑induced dedifferentiation and endoplasmic reticulum stress through inhibition of inositol‑requiring enzyme 1 downstream p38 kinase pathway in chondrocytes.

Molecular Medicine Reports, 2019
Gallotannin (GT) is a class of polyphenols with antioxidant, anticancer, and antiviral activities. 2‑Deoxy‑D‑glucose (2DG), a glucose‑derived molecule, can inhibit glucose metabolism and induce endoplasmic reticulum (ER) stress.
