Detailed explanation-1: -A condensation reaction between two monosaccharides forms a glycosidic bond. Disaccharides are formed by the condensation of two monosaccharides: maltose is a disaccharide formed by condensation of two glucose molecules.
Detailed explanation-2: -Starch is converted into maltose by an enzyme diastase. During this process, in this regime the diastatic enzymes start acting on the starches, breaking them up into sugars (hence the term saccharification).
Detailed explanation-3: -Starch is a condensation polymer made from glucose monomer units. When these large starch molecules react with water they break down into smaller sugar molecules. The starch is said to be hydrolysed. We can tell if starch has been hydrolysed by testing for the small sugar molecules that are formed in the process.
