Found Polysaccharide 58 times.

Displaying results 1 to 10.

1. Algin (alginate)
This gelatinous material, a polysaccharide extract from brown algae , is widely used in foods, medicines, and industrial and household products. The main algae that produce it are Laminaria species and Macrocystis pyrifera (a chemically different version of algin is produced by the bacterium Azobacter vinelandii.)

2. Amyloidosis
This is a condition in which a person's organ function is impaired by deposits of protein fibrils or proteins complexed with polysaccharide s. The symptoms are that of failure of the affected organs. Study of tissue samples (biopsy) definitively confirms the diagnosis.

3. Antigens
Molecules carried or produced by microorganisms that initiate antibody production; mostly proteins or proteins combined with polysaccharides .

4. Baculovirus
A genus of virus es which infect insects. They are used to control insects. They are also used to make protein s with polysaccharide s ( sugar chains) attached from cloned DNA , something which does not happen when proteins are made from cloned DNA using bacteria .

5. Biopolymer
Any macromolecule which can be found within a living thing, such as protein s (essentially long chains of amino acid s), nucleic acid s (such as DNA or RNA ), and polysaccharide s (long chains of simple sugar s).

6. Carbohydrate
A compound or molecule that is composed of carbon, oxygen and hydrogen in the ratio of 2H:1C:1O. Carbohydrates can be simple sugar s such as sucrose and fructose or complex polysaccharide polymer s such as chitin .

7. Carrageenan
A gel-forming polysaccharide goo found in the red algae Chondrus crispus and Gigartina mammillosa which is used as an emulsifier in foods, cosmetics and pharmaceuticals.

8. Cellulose
A polysaccharide that serves as a structural molecule in plants; only certain types of microbes can break down cellulose, and thus herbivores frequently harbor cellulose-digesting bacteria in their digestive systems. Cellulose is the main component of paper and can be used to synthesize alcohol .

9. Cellulose
A polysaccharide that is composed of unbranched chains of glucose ; the major structural carbohydrate of plants, insoluble in water, and indigestible in the human intestine.

10. Chitin
A polysaccharide that serves as a structural molecule in the shells of insects and crustaceans and in the flesh of fungi .
