Match each of the following aspects of triacylglycerols (TAGs) with the main structural feature which makes it possible. You may use each match only once. Ester linkages are vulnerable to hydrolysis. TAGS are not amphipathic. TAGS are hydrophobic and are stored anhydrously. Most of the carbons in TAG are highly reduced. 1. 2. 3. 4. TAGS can produce more energy per carbon than glycogen. TAGS can be stored safely, without danger of dissolving cell membranes. TAGS are a much lighter energy store than an equivalent amount of glycogen. The free fatty acids can be readily liberated from the TAGS when they are required for energy production.
1. Hypoxanthine is an unusual nitrogenous base that can be formed from adenosine; it is not normally found in nucleic acids. Hypoxanthine has a single ionizable group with a pKa of 8.7. If you dissolved hypoxanthine in an aqueous solution at pH 7.0, would this ionizable group be protonated or deprotonated?

Researchers have identified an enzyme that can catalyze two different chemical reactions. Which of the following is most likely true based on this finding? A B C D The reactants involved in the two reactions are very similar in their charge and shape. The reactant in one reaction acts as an allosteric inhibitor while the reactant in the sec- ond acts as an allosteric activator. The enzyme contains both alpha-helices and beta-sheets in their secondary structures. The catalytic activity of the enzyme is dependent on both competitive inhibition and al- losteric regulation.
