Concept introduction:
Maltose is a dissaccharide which consists of 2 units of glucose joined through glycosidic linkage.
When dissolved in water, glycosidic bond between the two monomer breaks down and produces glucose molecules.
Bond energy is the energy required for the formation or breaking the bond present between the atom of a molecule.The hydrolysis of disaccharide sugar can be determined by calculating the difference between the bond energy of reactant and product as follows:
dH = BE (reactant) - BE (product)

H-bonding is present in carbohydrates and proteins. Given the following
structures: (a) glucose, a monomer of carbohydrates, and (b) glycine, an
amino acid that is a protein building block, highlight the sites for H-bonding.

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?

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.
Consider a protein with five amino acids and three possible energy levels (separated by 1 J/mol) each amino acid can occupy.
At what temperature will there be 45% of molecules in conformation A and 55% of molecules in conformation B?
Comment on the size of this number and what distribution you would expect at room temperature. What does this mean about how "different" these energy levels are?
Look back at the figure and propose an error made in reporting units. What energy unit would have likely been more appropriate in this case?
