Abstract:The biochemical pathway regulating the synthesis of yellow/red pheomelanin is less well characterized than the synthesis of black/brown eumelanin. Inhibitor of gold (IG phenotype) is a plumage colour variant in chicken that provides an opportunity to further explore this pathway since the recessive allele (IG) at this locus is associated with a defect in the production of pheomelanin. IG/IG homozygotes display a marked dilution of red pheomelanin pigmentation, whilst black pigmentation (eumelanin) is only slig… Show more
“…Melanin can be oxidized and hydrolyzed to PDCA and PTCA in the alkaline environment of hydrogen peroxide ( Bi et al, 2023 ). Their different concentrations of 5, 10, 25, 50, 100, 250, and 500 ng/mL were used to make quantitative standard curves.…”
