- - - - lactose (milk sugar) is a disaccharide - formula C12H22O11 - consisting of one galactose unit and one glucose unit, combined. The two sugars are linked via a glycosidic bond - a beta 1-4 bond between galactose and glucose. This bond - effectively an oxygen bridge - is formed as a result of a condensation reaction.
- - - - Disaccharides consist of two monosaccharide units, linked together with glycosidic bonds in the α or β orientation. The most important of them are sucrose, lactose, and maltose
      - lactose
        
        Lactose is a disaccharide, meaning it's made up of two smaller sugar units. The sugar units, called glucose and galactose, both serve as sources of energy for your cells.
        
        In the intestine, lactose is transformed by lactase, an enzyme, into glucose and galactose, both simpler sugars, which are used by our body for energy and various functions.
        
        C12H22O11
        
        is a reducing sugar
        
        A sugar that serves as a reducing agent due to its free aldehyde or ketone functional groups
        
        is made up of two molecules that are aldoses
      - maltose
      - sucrose
        
        C12H22O11
        
        can undergo a combustion reaction to yield carbon dioxide and water.
        
        the monomer units are glucose and fructose
        
        is a product of photosynthesis

- - - - an enzyme in the small intestine, lactase breaks it down into simpler sugar forms, glucose and galactose.
