Inhibitory effect of enzymatic browning products on trypsin activity [PDF]
, 2011 The aim of this piece of work was to assay if the melanins synthesized from Agaricus bisporus polyphenol oxidase and one of its main substrates (L-tyrosine) act as trypsininhibitors, and therefore may have a toxic effect on protein digestion.

Fungal Melanins and their Potential Applications: A Review
BioResources, 2023 Melanins are complex molecules found in many organisms including bacteria, fungi, plants, and animals that have protective functions against stress. In fungi there are several biochemical routes for their synthesis, and their diversity and structural ...

Pigment Melanin: Pattern for Iris Recognition
, 2009 Recognition of iris based on Visible Light (VL) imaging is a difficult problem because of the light reflection from the cornea. Nonetheless, pigment melanin provides a rich feature source in VL, unavailable in Near-Infrared (NIR) imaging.

Fundamental building blocks of eumelanins: electronic properties of indolequinone-dimers
, 2003 We present results from the theoretical INDO calculations of the electronic structure for stacked eumelanins' monomers. As basic indolic components of the eumelanin structure 5,6-dihydroxyindole (DHI or HQ) and its oxidized forms (SQ and IQ) were chosen.

Eumelanin-based coloration and fitness parameters in birds: a meta-analysis [PDF]
, 2010 Although melanin is the most common pigment in animal integuments, the adaptive function of variation in melanin-based coloration remains poorly understood. The individual fitness returns associated with melanin pigments can be variable across species as

Biochemistry and biosynthesis of insect pigments
European Journal of Entomology, 2014 The functional role and commercial importance of insect pigments have been studied for well over a century. They are classified into those synthesized by insects, which include anthraquinones, aphins, pterins, tetrapyrroles, ommochromes, melanins and ...

Identification of 180 million years old, probably unchanged melanine [PDF]
The comparison of the infrared spectra of recent sepia melanine and of the content of the ink sac of fossilized cuttlefish indicates that the 180 million years old substance is unchanged melanine. Both substances behave identically on heating.

Carotenoids and their importance in the nutrition of fish and crustaceans [PDF]
, 1987 Carotenoids are quantitatively very prominent among the substances which render colour - Biochrome. There are an immense array of carotenoids in the animal kingdom and so also in the plants.
