(b)
Interpretation Introduction
Interpretation:
Given the reaction (a) was formed by hemiacetals (or) hemiketals and transformation process should be identified.
Concept Introduction:
Acetal formation: The small amount of acid catalysts is added to the reaction of an alcohol with an aldehyde or ketone, the hemi-space initially formed is converted into an acetal or a ketal substitution reaction.
Hemiketals: A compound with both an alcohol (-OH) groups and an ether (-OR) groups are bonded to the carbon atom that was at one time the ketone carbonyl carbon.

Draw the products formed when -D-idose is treated with C6H5NHNH2 (excess), H+
We have seen one of the four possible isomers of isocitrate, the one produced in the aconitase reaction. Draw the configurations of the other three.
a)
The equilibrium reaction for the aqueous dissociation of acetic acid is shown below.
CH3COOH(aq) = CH3COO-(aq) + H+ (aq)
Given the data in the table below and your knowledge of the "chemical standard
state" (X) and the “biochemical standard state” (Xº'), answer parts a) to e).
c)
For the dissociation of acetic acid at 298.15 K,
calculate AG and the corresponding pK₁.
b) Even though by definition, AfG©(H+ (aq)) = 0
and_AƒGº¹(H+(aq)) = 0, these are different
physical quantities. What precisely does each
