CARBOXIGLUTAMAT, s. m. / carboxyglutamate, s. m. / carbo- xyglutamate. Aminoacid rezultat prin y-carboxilarea unei mo- lecule de *glutamat inclusa Intr-o anumita molecula proteica, free- vent factor de coagulare (de ex.: protrombina, proconvertina, factor IX sau antihemofilic B, factor X sau factor Stuart). Acesti factori de coagulare sunt sintetizati si transformati In ficat In produsi biologic utilizabili de o proteincarboxilaza al carei co-factor este ‘vitamina K. ‘Osteocaldna In os si *aterocalcina In artere pot fi astfel carboxilate si, consecutiv, pot fixa cationii de Ca^.
