  • Title: [Metabolism of the Fe, Cu, Zn, Mg, MN and Co in the ovum of Cancer irroratus (decapod crustacean)].
    Author: Martin JL, Ceccaldi HJ.
    Journal: C R Seances Soc Biol Fil; 1976; 170(1):157-62. PubMed ID: 134767.
    Abstract:
    The concentrations of Fe, Cu, Zn, Mn and Co in the eggs of Cancer irroratus show variations in relation with time running out after laying, that is to say with embryogenesis. The increase of the rates of Fe, Mn and Mg is independant of the variations of the water content. Inversely, the decrease of Cu and Zn concentrations is in close relation with the increase of water content during the same period. The increase of Fe, Mn and Mg concentrations seems to be essentially under the dependance of physico-chemical, rather than biochemical, process in connection with the chitinous nature of the membranes surrounding the egg.
