What are polysaccharides PPT?
DEFINITION:- Polysaccharides are the complex carbohydrates. They are made up of chains of monosaccharide (the sugars) which are linked together by glycosidic bonds, which are formed by the condensation reaction.” Polysaccharides have a general formula of Cx(H2O)y .
What is polysaccharide and its types?
Sometimes known as glycans, there are three common and principal types of polysaccharide, cellulose, starch and glycogen, all made by joining together molecules of glucose in different ways. It has been estimated that 50% of the world’s organic carbon is found in one molecule; cellulose.
What are the 4 types of polysaccharides?
Types Of Polysaccharides
- Glycogen: It is made up of a large chain of molecules.
- Cellulose: The cell wall of the plants is made up of cellulose.
- Starch: It is formed by the condensation of amylose and amylopectin.
- Inulin: It is made up of a number of fructofuranose molecules linked together in chains.
What is polysaccharide classified?
Polysaccharides can be broadly classified into two classes: Homo-polysaccharides – are made up of one type of monosaccharide units. ex: cellulose, starch, glycogen. Hetero-polysaccharides – are made up of two or more types of monosaccharide units.
What is cellulose Slideshare?
Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth. Cellulose for industrial use is mainly obtained from wood pulp and cotton.
What is polysaccharide made of?
Polysaccharides are polymers consisting of chains of monosaccharide or disaccharide units joined by glycosidic bonds with different number of C (e.g. six for a hexose such as glucose).
What are the functions of polysaccharide?
Polysaccharides generally perform one of two functions: energy storage or structural support. Starch and glycogen are highly compact polymers that are used for energy storage. Cellulose and chitin are linear polymers that are used for structural support in plants and animals, respectively.
What is the structure of polysaccharide?
Polysaccharides consist of a succession of covalently linked monosaccharides (Shelke et al., 2014). The building blocks of 10 or more monosaccharide units are joined together by 1,4-glycosidic bonds to form cross-linked high–molecular weight polysaccharides.
What is polysaccharide formula?
Polysaccharides are polymeric carbohydrates composed of long chains of monosaccharide units joined by glycosidic linkages with a general formula of (C6H10O5)n, 40≤n≤3000.
What are the types of cellulose?
There are four different polymorphs of cellulose: cellulose I, II, III, and IV. Naturally occurring cellulose is known as cellulose I, which exists in parallel strands without intersheet hydrogen bonding. Cellulose II is thermodynamically more stable and exists in antiparallel strains with intersheet hydrogen bonding.
What are polysaccharides?
POLYSACCHARIDES 2. POLYSACCHARIDES • Simply glycans. • Repeat units of monosaccharides or their derivatives,held together by glycosidic bonds. • Linear as well as branched polymers. • Two types- 1.
What do you mean by Homopolysaccharides?
When all the monosaccharides in a polysaccharide are the same type the polysaccharide is called a homopolysaccharide or homoglycan. When the polysaccharides are composed of different types of sugars, referred to as polysaccharides/heteroglycans 31. 31 REFRENCES U.Satyanarayana, U.Chakrapani 2006 Biochemistry3rd edition.
