Definition of paracrystal in US English:



  • A piece of a substance that is not a true crystal but has some degree of order in its structure.

    • ‘The pH-related change in morphology of vinblastine (VLB)-induced paracrystals formed in Chinese hamster ovary (CHO) cells was examined immunohistochemically in order to determine both the mechanism of tubulin crystallization and the influence of acidic pHs on cytoskeletal microtubules.’
    • ‘In addition, e73 muscle contains dense aggregates that exhibit the periodicities typical of paramyosin paracrystals.’
    • ‘In a previous study it was demonstrated that in plasmolysed dividing leaf cells of Chlorophyton comosum all microtubule arrays were disintegrated and free tubulin was incorporated into macrotubules and tubulin paracrystals.’
