Tracking the melanogenic pathway to unravel the functional role of melanins: the bottom-up approach
, 2023 Investigation of the structural features of melanins, both the dark eumelanins and the reddish brown variants pheomelanins, has ever represented a formidable challenge because of the minute amounts occurring in the natural sources, the molecular ...

Studying grain color diversity in the barley collection of VIR
Труды по прикладной ботанике, генетике и селекции, 2022 Background. Dark color of barley grain (Hordeum vulgare L.) can be caused by the synthesis and accumulation of two types of polyphenolic pigments – anthocyanins and melanins, which perform important functions in plant life, participating in the ...

Melanins in fungi: Types, localization and putative biological roles [PDF]
, 2021 Melanin is a secondary metabolite made up by complex heterogeneous polymers. Several classes of fungal melanins have been described like γ-glutaminyl-3,4-dihydroxy-benzene (GDHB)-, L-DOPA-(eumelanin), DHN-, catechol-melanin, pyomelanin, p-aminophenol ...

Advanced Science, EarlyView.Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized
