Structure of maltose :
`to` Maltose is formed from two `alpha` - glucose units (Disaccharide)
`to` C-1 of the glucose linked to C-4 of another glucose
`to` It is reducing sugar because C-1 of `2^(nd)` glucose is solution have free aldehyde group
`to` maltose on hydrolysis to form two glucose units
`underset("maltose")(C_12H_22O_11 + H_2O) to underset("glucose")(C_6H_12O_6)+underset("glucose")(C_6H_12O_6)`
Structure of lactose :
`to` Lactose is milk sugar
`to` Lactose is formed by the combination `beta` - glucose and `beta` - galactose (Disaccharide)
`to` It is a reducing sugar.
`to` Lactose on hydrolysis to form glucose and galactose
`underset("Lactose")(C_12H_22O_11) + H_2O to underset("glucose")(C_6H_12O_6) + underset("galactose")(C_6H_12O_6)`
