Weba Phosphate Group. …. Nucleotides are joined together by a Condensation Reaction between the Phosphate Group of one and the Sugar Group of another. The bond between the two monomers is called a Phosphodiester Bond. Many nucleotides joined together in this way make a repeating Sugar-Phosphate ‘backbone’ out of which the organic bases project. WebStarch consists of a mixture of Amylose and a branched carbohydrate chain called Amylopectin. The branches are formed when a one end of a chain joins with a glucose in another, forming a (1→4) Glycosidic Bond. (1→4) and (1→6) glycosidic bonds in amylose and amylopectin.

WebPolymers are macromolecules made up of repeating units called monomers. Polymers can be synthesized through two types of polymerization reactions i.e. addition and condensation polymerization. Polymers exist as amorphous or crystalline solids. Polymers can be classified as organic, inorganic, synthetic and mixture of organic-inorganic polymers.
