A carbohydrate contains carbon, hydrogen and oxygen.
Glucose, fructose and galactose are monosaccharide's, they all have the formula
which is C6H12O6 but they have different shapes therefore they are called isomers.
Sucrose, maltose and lactose are disaccharides they have the formula C12 H22 O11
because it is double the monosaccharide's because there is two joined together but a
H2O atom is removed from the condensation reaction of them bonding.
Starch is many molecules of glucose joined together, this is a polysaccharide.
Alpha glucose…read more

Condensation Reaction
Condensation reactions join monosaccharide's and disaccharides
together to form a glycosidic bond between them. H20 is released.…read more

Hydrolysis is the reaction to break a disaccharide into two
monosacchardies, to do this we use hydrolysis where an enzyme and
water is required to break the glycosidic bond down.…read more

Glucose + Glucose = Maltose + H2O(condensation)
Glucose + Fructose = Sucrose + H2O(condensation)
Glucose + Galactose = Lactose + H2O(condensation)
C6H12O6 + C6H12O6 = C12 H22 O11 + H2O…read more
