Question

Name some disaccharides. Give the formula.

Short answer

Question: Name some common disaccharides and provide their chemical formulas. Answer: Some common disaccharides are sucrose, lactose, and maltose. Their chemical formulas are as follows: - Sucrose: C12H22O11 - Lactose: C12H22O11 - Maltose: C12H22O11

Step-by-step solution

1. Identify common disaccharides.

Some common disaccharides include sucrose, lactose, and maltose.

2. Determine the chemical formula for sucrose.

Sucrose is composed of one glucose (C_6H_12O_6) and one fructose (C_6H_12O_6) molecule bonded together. Note that the bond between the two sugar molecules involves the removal of a water molecule (H_2O). Hence, the chemical formula for sucrose is C_12H_22O_11.

3. Determine the chemical formula for lactose.

Lactose is composed of one glucose (C_6H_12O_6) and one galactose (C_6H_12O_6) molecule bonded together. Similar to sucrose, the bond between the two sugar molecules involves the removal of a water molecule (H_2O). Therefore, the chemical formula for lactose is C_12H_22O_11.

4. Determine the chemical formula for maltose.

Maltose is composed of two glucose (C_6H_12O_6) molecules bonded together. Like sucrose and lactose, the bond between the two glucose molecules also involves the removal of a water molecule (H_2O). Hence, the chemical formula for maltose is C_12H_22O_11.
