1. Cellulose (cellulose)
.Cellulose, polysaccharide is very small, a bar (rod-shaped units) is called a micelle (micells) sometimes carries a large unit of micelle 10 to 20 units. A microfibril (microfibril) which are characterized mainly as the crystal structureAre difficult to be decomposed. The most common is the organic component of all 45% organic in nature. Most are produced by photosynthesis process of plants, and accumulate in the cell wall, such as cotton.97-99 classified as pure cellulose polymer consisting of lines arranged in parallel. And adhere together with strong dispersion (dispersion forcc) and hydrogen (hydrogen bond) within the cellulose is based on molecular bonding tightly apply cellulose paint reaction with different substancesThe substance can't come through in the cellulose, is also found in several kinds of algae and fungi, including animal ในสั sea species.In the structure of cellulose were connected by a bonding wire, beta - 1 4 - glycosidic. The tile is a line where no different branches. The number of units came to depend on the type and the age of the plant, may be 200-15000 unit or a million units con fig deacetylation (configulation) of beta - good - glucosamine โคไฟ RA Cronos (β - D-glucogyranose) mainly be style chairs. (chair form) (images 1) and molecules of glucan will have skin (surface) is a hydrogen atom.(hydrophobic) together by bonding, beta - 14 - glycosidic, therefore the force applied to the line Lu can rotate twist has 180 degrees around an axis. Thus apply to each cable shape is like a ribbon. (flat ribbon) line Lu can each line is lined up as microfibrils.Roll or overlapping spiral around the axis of the fiber. The alignment of the molecules of cellulose such paint can be divided into the shape of the cellulose in the walls of plant cells 3. Is different, as shown in the picture, 2 (Norkrans1967) from studies using X-ray differential factor collection (X-ray diffraction), it was found that the microfibrils arranged with some example regulation (crystalline). But some events at sixes and sevens (amorphous), which is part of the natural order of 85.15 plant cell wall is captured in a strip of cellulose, not contact each other throughout. Separated by gaps. When the cells to fully within the spaces are filled with lignin. The apply of cellulose are covered by lignin.
