Chapter 24, Problem 24.71GP
In the synthesis of cholesterol, acetyl-CoA is converted to 2-methyl-1,3-butadiene. Molecules of 2-methyl-1,3-butadiene are then joined to give the carbon skeleton of cholesterol. Draw the condensed structure of 2-methyl-1,3-butadiene. How many carbon atoms does cholesterol contain? What minimum number of 2-methyl-1,3-butadiene molecules is required to make one molecule of cholesterol?

- The titration curve of alanine shows the ionization of two functional groups with pK values of 2.34 and 9.69, corresponding to the ionization of the carboxyl and the protonated amino groups, respectively. The titration of di-, tri-, and larger oligopeptides of alanine also shows the ionization of only two functional groups, although the experimental pK values are different. The table summarizes the trend in pK values.

The three peptides are impurities in the original chymotrypsin sample. Performic acid cleaves proteins on the carboxyl-terminal side of lysine and arginine residues. Performic acid cleaves the disulfide bonds holding together the three subunits of chymotrypsin. Correct Answerarrow_forward
