Polysaccharides Carbohydrates that cellulose

In the present work, we extend the method to compensate for the hydrogen bonds present in carbohydrates. The hydroxylated character of carbohydrate polymers influences between-chain interactions through networks of hydrogen bonds that occur during crystallization. Frequently, several possible attractive interactions exist that lead to different packing arrangements, and several allomorphic crystalline forms have been observed for polysaccharides such as cellulose, chitin, mannan and amylose. The situation is even more complex when water or other guest molecules are present in the crystalline domains. Another complication is that polysaccharide polymorphism includes different helix shapes as well. [Pg.282]

Glycoside hydrolases (glycosidases) are essential and consequently widely abundant enzymes in all living systems that rely on the processing of carbohydrates. From the degradation of such polysaccharides as starch, cellulose, or chitin to the highly... [Pg.193]

Polysaccharides are carbohydrates that can be hydrolyzed to many monosaccharide units. Polysaccharides are naturally occurring polymers (biopolymers) of carbohydrates. They include starch and cellulose, both biopolymers of glucose. Starch is a polysaccharide whose carbohydrate units are easily added to store energy or removed to provide... [Pg.1102]

The major kinds of digestible carbohydrates in foods are the simple sugars (glucose and fructose), disaccharides (sucrose, maltose, and lactose), and polysaccharides (amylose and amylopectin in starch from plants, and glycogen from meat). The indigestible carbohydrates include cellulose and its derivatives, pectin (the substance that makes jam and jelly gel), and plant gums. [Pg.403]

Biopolymers are polymers produced by living organisms. They contain monomeric units that are covalently bonded to form larger structures. There are three main classes of biopolymers based on the differing monomeric units used and the structure of the biopolymer formed. Polynucleotides are long polymers which are composed of 13 or more nucleotide monomers, Polypeptides are short polymers of amino acids and polysaccharides are often linear bonded polymeric carbohydrate stmctures. Cellulose is the most coimnon organic compound and biopolymer on earth. About 33 percent of all plant matter is cellulose. The cellulose content of cotton is 90 percent and that of wood is 50 percent. [Pg.3]

A disaccharide consists of two monosaccharide units joined together. For example, ordinary table sugar, sucrose, is a disaccharide that contains one molecule of glucose and one molecule of firactose. Polysaccharides are carbohydrates that are naturally occurring polymers such as amylose and cellulose, which contain many monosaccharide units of glucose. Although we... [Pg.263]
