Final answer:
To name the monosaccharides in the images, one would need to identify their structural differences. However, without the images, we cannot name them; the key monosaccharides to look for are glucose, galactose, and fructose, which are all isomers of C6H12O6.
Step-by-step explanation:
To name the monosaccharides in the images, we need to identify their structural differences. Monosaccharides are simple sugars that serve as building blocks for more complex carbohydrates. Glucose, galactose, and fructose are all common monosaccharides. While glucose and galactose are both aldohexoses, fructose is a ketohexose. The difference lies in the placement of their carbonyl groups (=O): in glucose, the aldehyde group is at carbon number one (C#1), whereas in fructose, the keto group is at carbon number two (C#2). All these sugars have the same chemical formula C6H12O6 but differ in their structural arrangement, which makes them isomers.
Based on the clues provided, where we mention that glucose combines with fructose to form sucrose, glucose combines with galactose to form lactose, and two glucose molecules combine to form maltose, this helps us clarify which monosaccharides are paired in each of these disaccharides.
Therefore, in the context of the images representing the structures of monosaccharides, without the images, we cannot confidently decide which labels apply. However, the key monosaccharides to look for would be glucose, galactose, and fructose based on the information provided in the reference.
