Question

compare the chemical structure of maltose to lactose and sucrose.
complete the sentences.
maltose is a dropdown made of the dropdown glucose. compared to lactose and sucrose, maltose has dropdown carbon, hydrogen, and oxygen atoms

Explanation:

1. Maltose is a disaccharide (formed by two monosaccharides). From the structure, maltose is made of two glucose units.
2. The molecular formula of maltose, lactose, and sucrose is all \( C_{12}H_{22}O_{11} \), so maltose has the same number of carbon, hydrogen, and oxygen atoms as lactose and sucrose.

For the blanks:

• First blank: disaccharide (since it's formed by two monosaccharides, glucose + glucose)
• Second blank: two (maltose is two glucose molecules linked)
• Third blank: the same number of (as lactose and sucrose also have \( C_{12}H_{22}O_{11} \))

Answer:

• Maltose is a \(\boldsymbol{\text{disaccharide}}\) made of the \(\boldsymbol{\text{two}}\) glucose. Compared to lactose and sucrose, maltose has \(\boldsymbol{\text{the same number of}}\) carbon, hydrogen, and oxygen atoms.
