Do glucose and galactose have the same chemical formula with different structures making them isomers? True or False?

True. Glucose and galactose both have the chemical formula C₆H₁₂O₆, which means they are monosaccharides made up of the same number and type of atoms. However, they differ in their structural arrangement, which classifies them as isomers. Specifically, glucose is an aldohexose, containing an aldehyde group, while galactose is a hexose that features a different arrangement of hydroxyl groups, classifying it as a ketohexose in some contexts. These structural differences lead to variations in their properties and functions within biological systems.
