Explain what structural properties of triacylglycerols makes them a storage form of fatty acids in adipose tissues. 

A biochemical pathway produces metabolite E. This pathway consists of A, B, C and D intermediates that require enzymes 1, 2, 3 and 4 to catalyze each step of the reaction. Given the following information about each reaction, is this pathway overall anabolic or catabolic? Give reason for your answer. A–>B–>C–>D–>E A  → B, ΔG = -8 B → C, ΔH = -4, TΔS = 6 C→ D, ΔH = 2, TΔS = -6 D→ E, ΔG = +2
