What is the chemical formula for maltose (a disaccharide)?
|
C6H26O6
|
|
C12H24O12
|
|
C12H22O11
|
|
C12H22O12

Explanation:
Detailed explanation-1: -Maltose is a disaccharide whose molecular formula is C12H22O11. Placing maltose under acidic conditions will hydrolyze it into two identical glucose sugars.
Detailed explanation-2: -Sucrose (common name: table sugar, also called saccharose) is a disaccharide (glucose + fructose) with the molecular formula C12H22O11.
Detailed explanation-3: -Because maltose is made up of two glucose units, the formula for maltose must be C12H24O12. However, when two glucose molecules and a glycosidic bond are formed between two glucose units during polymerization, a water molecule is lost. As a result, maltose’s chemical formula is C12H22O11, not C12H24O12.
