What are monomers and polymers? Explain with example.
The word monomer comes from mono-(one) and -mer (part). Monomers are small molecules which may be joined together in a repeating fashion to form more complex molecules called polymers. Monomers form polymers by forming chemical bonds or binding supramolecularly through a process called polymerization
A monomer is a small molecular sub unit that can be combined with similar sub units to form larger molecules. In living systems, like our own bodies, these larger molecules include carbohydrates, lipids, nucleic acids and proteins. Following diagram represents a number of monomers.
Example of Monomers are:-
1). Monosaccharides (simple sugars)
2). Amino-acids
3). Nucleotides
A polymer is a large molecule made up of chains of repeating basic molecular units called monomers. Many polymers are named by their basic monomer unit with the prefix poly. Polyvinyl chloride (PVC) is the polymer of vinyl chloride.
Proteins and DNA are natural polymers where amino acids are the monomer units.
Example of Polymers are:-
1). Polysaccharides
2). Polypeptides and proteins
3). Nucleic acids
