Which triacylglycerol yields more energy on oxidation: one containing three resides of linolenic acid or three residues of stearic acid?
Explain why it fully reduced and what is being fully reduced
Homework Answers
The triacylglycerol containing the stearic acid residues yields more energy since it is fully reduced
Stearic acid gets reduced and desaturates into oleic acid

1. Explain why polyaspartatic acid (a peptide containing only aspartic acid residues) does NOT form an alpha helix at pH 7.0 but can at pH 2. 6. 2. What kind of non-covalent interaction would the following pairs of amino acids have in the three dimensional structure of a protein at pH 7.0? a) His-Asp b) Tyr-Asp c) Val-Leu d) Trp-Gln 3.

1(a) The complete metabolic oxidation of glucose to CO2 and O2 yields 38 ATPs. What is the yield of ATP from Glc if it is first added to a glycogen polymer before being converted to CO2 and O2? What is the FRACTIONAL energetic cost in terms of ATP (eg., 1%, 2%, 10%, etc.) of storing glucose as glycogen and later metabolizing the glycogen rather than directly metabolizing the glucose? Be sure to show your work and state any assumptions being...
