Question

select the true statements.
sucrose and lactose have different chemical structures.
the monosaccharides in lactose are galactose and glucose.
sucrose and lactose have the same chemical formula.
the monosaccharides in sucrose are fructose and glucose.

Explanation:

• Sucrose is formed by glucose and fructose, while lactose is formed by glucose and galactose. So their chemical structures are different.
• Lactose is a disaccharide composed of galactose and glucose.
• Both sucrose and lactose have the chemical formula \(C_{12}H_{22}O_{11}\).
• Sucrose is made up of fructose and glucose.

Answer:

All the statements are true.
