Are there chemical differences between galactose, glucose, and mannose? Identify the statement that is not true.
A) All three sugars (galactose, glucose, and mannose) are monosaccharides, which means they are simple sugars composed of a single sugar molecule.
B) Galactose and glucose are both aldoses, while mannose is a ketose. This structural difference distinguishes them chemically.
C) Galactose, glucose, and mannose are all hexoses, meaning they have six carbon atoms in their molecular structure.
D) The primary structural difference between these sugars is the orientation of the hydroxyl group on the fourth carbon atom, which differs among galactose, glucose, and mannose.
