Cellulose as polymer of glucose
Cellulose (C6H10O5)n is a long-chain polymeric polysaccharide carbohydrate, of beta-glucose. It forms the primary structural component of green plants.

Cellulose is a common material in plant cell walls and was first noted as such in 1838. It occurs naturally in almost pure form only in cotton fibre; in combination with lignin and any hemicellulose, it is found in all plant material.

Cellulose is probably the single most abundant organic molecule in the biosphere. It is the major structural material of which plants are made. Wood is largely cellulose while cotton and paper are almost pure cellulose.

Cellulose and Chitin are polysaccharides that function to support and protect the organism. The cell walls of plants are composed of cellulose. The cell walls of fungi and the exoskeleton of arthropods are composed of chitin.

cellulose -- carbohydrate polymer of the simple sugar glucose. It is found in the cell walls of plants and green algae, as well as dinoflagellates. Cellulose is the most abundant compound on earth that is manufactured by living things.

Then a nitrocellulose or nylon membrane is layed on top of the agarose gel and absorbant paper is layered on top of the membrane. The aqueous solution passes from the agarose gel through the membrane into the absorbant paper by capillary action.

Transfer by absorption of DNA fragments separated in electrophoretic gels to membrane filters (nylon or nitrocellulose) for detection of specific base sequences by radiolabeled complementary probes.

The samples are spotted onto a hybridization membrane (such as nitrocellulose or activated nylon, etc.), fixed and hybridized with a radioactive probe.

Next the ssDNA was blotted and trapped on nitrocellulose filter paper. The researchers then added single-stranded homeobox DNA, which had been labeled with a radioactive isotope, to the filter paper.

Note that some explosive materials can fall into either category, according to how they are initiated. For example, nitrocellulose deflagrates if ignited, but detonates if initiated by a strong detonator.
