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. Glycogen is almost identical to starch but differs in that the chains ... WebAmino acids react by condensation polymerisation. so for every monomer which is added to the growing polymer chain, one molecule of water is also produced. For example, glycine is the simplest ...

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.

WebAnswer 1: When ethenol (CH (OH)=CH 2) is polymerised, the C-C double bond opens to produce a repeating unit of CH (OH)-CH 2. This gives the polymer poly (ethenol) Answer 2: … WebAddition polymers are made from molecules containing C=C bonds. Polymers have different uses that depend on their properties. DNA, starch and proteins are biological polymers.
