Summary Introduction
To review:
The order of reactivity in nucleophilic substitution reactions: phosphate>thiols>esters>amides, based on the pKa values. pKa values are given as: phosphoric acid- 1×10-3, hydrogen sulfide- 1×10-7, alcohols- 1×10-17 and ammonia- 1×10-36 .
Introduction:
pKa is an acid dissociation constant; it gives a quantitative measure of an acid’s strength in a solution. It shows the tendency of an acid to be able to lose a proton. The more positive the value of pKa, the smaller is the extent of dissociation.

When a purine or a pyrimidine is linked through a β-N-glycosidic link to C-1 of a pentose, the molecule is called a _____________ .
Protease is an enzyme that catalyzes the breaking of amide bonds which is very stable at “mild” conditions, namely body temperature and pH 7 (if done in the lab requires hot conditions, concentrated HCl for hours). Some proteases have two aspartic acid residues at their active sites. Write the reaction mechanism (which follows general acid-base catalysis)

Acid phosphatases are produced by erythrocytes, the liver, kidney, spleen, and prostate gland. The enzyme from the prostate gland is clinically important because an increased activity in the blood is frequently an indication of cancer of the prostate gland. The phosphatase from the prostate gland is strongly inhibited by tartrate ion, but acid phosphatases from other tissues are not. How can this information be used to develop a commercial specific procedure for measuring the activity of the acid phosphatase of the prostate gland in human blood serum? * 1. Prostate cancer cannot be diagnosed biochemically. 2. Use tartrate to inhibit phosphatase from prostate gland and then subtract the results from the total serum enzyme activities to get an…arrow_forward
