Question

maltose is a disaccharide found mostly in the seeds of wheat, oats, rice, barley, rye, and millet. the model shows the chemical structure of maltose. compare the chemical structure of maltose to lactose and sucrose. complete the sentences. maltose is a made of the glucose. compared to lactose and sucrose, maltose has carbon, hydrogen, and oxygen atoms.

Explanation:

1. Maltose is a disaccharide (since it's made of two monosaccharides, as seen from its structure with two glucose units).
2. Maltose is made of two glucose molecules (the structure shows two glucose rings linked).
3. Comparing the formulas \( C_{12}H_{22}O_{11} \) for all three (maltose, lactose, sucrose), they have the same number of carbon, hydrogen, and oxygen atoms (since all three have the formula \( C_{12}H_{22}O_{11} \)).

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.
