Question

condensation reaction of lactose,fructose,sucrose,maltose and starch.

Answer 1

The condensation reactions and the products are as below.

1. The condensation of beta D galactose and alpha D glucose yields Lactose

2. The condensation of glucose with fructose yields Sucrose

3. The condensation of two molecules of glucose yields Maltose

4. Starch is the polysaccharide and is formed by condensation polymerization and has multiple glycidic bonds. A starch is a complex sugar and has a general formula (C₆H₁₀O₅)_n . Starchis a polysaccharide comprising glucose monomers joined in α 1,4 linkages.

5. Fructose is a monomer and it condenses with other sugars to yield the dimers through the glycidic bonds.
