Which polysaccharide component of carbohydrates is commonly present in bread?
Solution
Hint: A polysaccharide is a large molecule which consists of many smaller monosaccharides.
Complete step-by-step answer:
Monosaccharides are pure sugars, such as glucose. Such small monomers are bound together by special enzymes that produce large sugar polymers, or polysaccharides. A glycan is often called a polysaccharide. A polysaccharide can be a homopolysaccharide, where all the monosaccharides are the same, or a heteropolysaccharide in which the monosaccharides differ. Depending on which monosaccharides are linked, and which carbons are associated in the monosaccharides, polysaccharides take different forms. A molecule with a straight chain of monosaccharides is considered a linear polysaccharide, whereas the branched polysaccharide is defined as a chain that has arms and turns.
The main component of polysaccharide present in bread is starch.
Starch is a carbohydrate obtained from agricultural raw materials that is commonly used in literally thousands of uses in daily food and non-food. This is the main carbohydrate in the human diet. Since it is organic and biodegradable, it is also a good raw material in many chemical applications such as plastics, detergents, glues etc. as a replacement for fossil-fuel components. The starch molecule is composed of a large number of units of glucose joined by glycosidic bonds. Both vegetables make it into an energy shop.
Note: Pure starch is an insoluble white, tasteless, and odorless powder in cold water or alcohol. It consists of two types of molecules: linear and helical amylose, and amylopectin, branched. Starch usually contains 20 to 25 per cent amylose and 75 to 80 percent amylopectin by weight, depending on the plant. Glycogen, the animal glucose store, is a more highly branched amylopectin variety.
