Detection of Unit Cell Parameters of CelluloseIntroduction of detection services of unit cell parameters of cellulose Cellulose is a linear polymer composed of glucose. The presence of a large number of hydrogen bonds between and within glucose molecule chains allows them to aggregate to form multi-layered, aggregated state structures such as microfibrils, fibrils and fibers. Six interconvertible polycrystalline cellulose types have been identified, including cellulose I, II, IIII, IIIII, IVI and IVII. The natural cellulose found in most plant cell walls is cellulose I, which has two isomorphs: the predominant cellulose Iα with a triclinic unit cell and a small amount of Iβ with a monoclinic unit cell. The study of cellulose structure is usually analyzed at the holistic and ultrastructural levels. The detection of cellulose unit cell parameters is helpful for resolving the structure of crystalline cellulose, thus greatly improving the understanding of cellulose. In addition, the establishment of quantitative methods to characterize the supramolecular structure of natural cellulose is of great significance for the study of enzyme reaction kinetics, the synergy between enzyme components and the reaction mechanism in the process of material transformation.
