纤维素，Cellulose；acid washed, from spruce, for column chromatography

Cellulose, a homopolymer consisting of glucose units joined by beta-1,4 bonds. These are strongly attached through inter and intramolecular hydrogen bonds and van der Waals forces resulting in microfibrils which together form fibers. They are arranged in parallel reducing ends of adjacent glucan chains. Cellulose is widely used as sorbent in TLC.

 

Cellulose was used to measure the cyrstallinity index using X-ray diffraction (XRD) patterns and solid-state 13C nuclear magnetic resonance spectra.
