  • Title: Has removal of excess cysteine led to the evolution of pheomelanin? Pheomelanogenesis as an excretory mechanism for cysteine.
    Author: Galván I, Ghanem G, Møller AP.
    Journal: Bioessays; 2012 Jul; 34(7):565-8. PubMed ID: 22442057.
    Abstract:
    Pheomelanogenesis may have evolved as an excretory mechanism to remove excess cysteine, and in humans this might potentially confer a greater ability to avoid disease such as Parkinson's and Alzheimer's disease, in which excess cysteine is a contributory cause.
