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 (a type of carbohydrate formed by two monosaccharides) made of two glucose units (as seen in its structure: two glucose molecules linked).
2. Lactose is made of glucose and galactose, sucrose is made of glucose and fructose. Maltose, lactose, and sucrose all have the same molecular formula \( C_{12}H_{22}O_{11} \), 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 from two monosaccharides, glucose + glucose)
• Second blank: two (or "same" in terms of type? Wait, maltose is two glucose, so "two" or "a pair of" or "two molecules of" — but from the structure, it's two glucose units)
• Third blank: the same number of (since all three have \( C_{12}H_{22}O_{11} \))

Answer:

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