Question
Galactose and glucose have the same molecular formula, and the only difference
is the orientation of the hydroxyl bond at the 4' position. Why is this type of
distinction of bond orientations important in biology?

Galactose
Glucose
Glucose can be metabolized into energy, but galactose cannot.
The bonds have different polarity, so they form hydrogen bonds with different
strengths.
O Enzymes and binding proteins are specific enough to detect the different
configurations and must bind one sugar or the other.
O The two forms switch back and forth spontaneously, which makes the molecules more
flexible and versatile.
