Concept introduction:
A polymer is a long chain consists of large number of monomer units. In a polymer, the monomers are linked to each other in a continuous or repetitive manner. These monomer units are linked to each other either through the formation of peptide linkage, glycosidic linkage or by removal of any moiety such as a water molecule. Polyvinyl chloride, Bakelite and polystyrene are some of the examples of the

Interpretation:
The difference between polyester and polyamide needs to be explained.

Interpretation:
The difference between alpha and beta glucose needs to be explained.
Concept introduction:
Glucose is the simplest carbohydrate with molecular formula C6 H12 O6 . It is also known as aldohexose because it contains an
The hemiacetal form of the glucose exists in two forms that is alpha and beta depending on the position of 1 of the 4-hydroxyl groups in the cyclic ring.
