“…The Polymer contains free hydroxyl group at the C-2, C-3 and C-6 atoms. Based on the OH groups and oxygen atoms of both the pyranose ring and the glycosidic bonds, ordered hydrogen bond systems from various types of supramolecular semi-crystalline structures (Atalla et al, 1993 andBrown et al, 2000) (Fig. 1).…”

This review attempts to bring together basic and systematic information which has been gathered on cellulose structure, types, principally that of native cellulose, over the last few decades. Even though advances have been made in the field of crystallography, powder crystallography cannot yield a definitive cellulose structure and single crystal diffraction is not possible due to the lack of suitable crystals. Knowledge obtained on the biosynthesis of native cellulose and on the polymorphy of cellulose and its derivatives help our understanding of ultrastructure. Many inconsistencies between early crystallographic studies of native cellulose have been clarified by the discovery that two polymorphs (α and β) of cellulose I exist. Models of the possible ultrastructural arrangements within native cellulose have been put forward over the decades; with advancement in technology, computer simulations of small and large systems are being created to test the viability of these ultrastructural models. It is hoped that this review will aid in the understanding of the complexity and uncertainties that still exist in this subject.

“…It is 25-30 nm in diameter (Mueller and Brown, 1980;Delmer, 1999). Each subunit of CelS has six CESA isoforms which produce six glucan chains (Brown and Saxena, 2000). The CelS is thus theoretically composed of 36 CESAs.…”

Annually, plants produce about 180 billion tons of cellulose making it the largest reservoir of organic carbon on Earth. Cellulose is a linear homopolymer of beta(1-4)-linked glucose residues. The coordinated synthesis of glucose chains is orchestrated by specific plasma membrane-bound cellulose synthase complexes (CelS). The CelS is postulated to be composed of approximately 36 cellulose synthase (CESA) subunits. The CelS synthesizes 36 glucose chains in close proximity before they are further organized into microfibrils that are further associated with other cell wall polymers. The 36 glucose chains in a microfibril are stabilized by intra- and inter-hydrogen bonding which confer great stability on microfibrils. Several elementary microfibrils come together to form macrofibrils. Many CESA isoforms appear to be involved in the cellulose biosynthetic process and at least three types of CESA isoforms appear to be necessary for the functional organization of CelS in higher plants.

“…Как дешевый возобновляемый источник биосов-местимых и биоразлагаемых натуральных материалов целлюлоза приобретает все большее значение для производства новых экологически чистых функциональных материалов. Целлюлозу в основном выделяют из растений, хотя она может быть выделена, например, из туникатов, некоторых бактерий и плесени [2]. Волокна целлюлозы состоят из пучков микрофибрилл, образованных цепочками β-(поли-1,4-D-глюкозы).…”
