Polysaccharides

Complex carbohydrates formed by the condensation of large numbers of monosaccharide units, e.g. starch, glycogen, cellulose, dextrins, inulin. On hydrolysis the simple sugar is liberated.


Carbohydrate compounds like starch, cellulose, and pectic substances.


Carbohydrate form that yields more than two simple sugars upon breakdown, found in cereal grains, roots, bulbs, and tubers. The principle ones are starch, dextrin, glycogen, and cellulose.


Linear and/or branched (structure) macromolecules (i.e., large molecules) composed of many monosaccharide units (monomers such as glucose) linked by glycosidic bonds.


The complex carbohydrates starches, cellulose, and glycogen.


A type of carbohydrate. It contains sugar molecules that are linked together chemically.


A carbohydrate that may be broken down by hydrolysis into two or more molecules of monosaccharides.


A type of carbohydrate made up of a lot of monosaccharides joined together in chains. They include starch and cellulose, are insoluble in water and do not form crystals.


A string of monosaccharides joined together. If the linkage is an α-1,4 or α-1,6, mammalian enzymes can break the bond. If the linkage is a β-linkage, mammalian saccharidases cannot sever it.


A polysaccharide is a carbohydrate containing more than two monosaccharides linked by glycosidic bonds. The most common polysaccharides provided in the diet are amylose and amylopectin, which are often collectively referred to as starches.


Complex carbohydrate (e.g., starch) that can be broken down into simpler monosaccharides, such as sugar.


A carbohydrate formed from many monosaccharides joined together in long linear or branched chains. Polysaccharides have two important functions: (1) as storage forms of energy; for example glycogen in animals and man and starch in plants, and (2) as structural elements; for example mucopolysaccharides in animals and man and cellulose in plants.


A carbohydrate comprising several monosaccharides linked in long chains. Polysaccharides store energy as starch in plants and glycogen in animals and they also form the structural parts of plants (as cellulose) and animals (as mucopolysaccharides).


One of a group of carbohydrates that, upon hydrolysis, yield more than 20 monosaccharide molecules. They are complex carbohydrates of high molecular weight, usually insoluble in water, but when soluble, they form colloidal solutions. Their basic formula is (C6Hi206)n. They include two groups: starch (e.g., starch, inulin, glycogen, dextrin) and cellulose (e.g., cellulose and hemicelluloses). The hemicelluloses include the pentosans (e.g., gum arabic), hexosans (e.g., agaragar), and hexopentosans (e.g., pectin).


Carbohydrates such as starch that contain three or more simple carbohydrate molecules.


A group of intricate carbohydrates comprised of a plethora of sugar units chemically joined together.


A intricate form of carbohydrate composed of extensive chains of monosaccharides linked together is known as a polysaccharide.


A polysaccharide is a carbohydrate made up of numerous monosaccharides, or simple sugar units, linked together. Some examples of polysaccharides are glycogen, the primary way carbohydrates are stored in the body; starch, a carbohydrate sourced from fruits, vegetables, and grains; and cellulose, a non-digestible substance found in plant-derived foods.
