Monosaccharides
Captions available
The idea
A monosaccharide is a single simple sugar, the basic monomer that carbohydrates are built from.
In practice
Glucose, galactose, and fructose are all monosaccharides sharing the same chemical formula but differing in the arrangement of their atoms.
Where people slip
Sharing a chemical formula does not make two monosaccharides identical — their differing atomic arrangement changes how the body uses each one.
