Structure and biomedical importance of disaccharides.
Answer:

Structure:

Disaccharide consists of two monosaccharide units either similar or dissimilar held together by a glycosidic bond.

Different types of disaccharides and their structures are as follows.

1. Reducing disaccharides:

1. Maltose:
   • It consists of two a-D-glucose units held together by a (1→4) glycosidic bond.
   • It contains a free aldehyde group on C of second glucose.
2. Lactose:
   • It consists of P-D-galactose and P-D-glucose held together by a P(1→4) glycosidic bond.
   • The anomeric carbon of C} glucose is free for reducing reactions.

2. Non-reducing disaccharides:

1. Sucrose:
   • It consists of a-D-glucose and p-D-fructose held by a glycosidic bond between Cl of a-glucose and C2 and P-fructose.
