You are given a mixture of 3 amino acids Gly, Asp, and Ile with PI values of  5.6, 2.95 and 8.86. You run an isoelectric focusing at a pH of 3. Explain what happens once the power is turned on.

ATP stores energy through its ability to lose a phosphate group to form ADP in the following reactionATP+H2O→ADP+phosphateAt body temperature, the thermodynamic values for ATP hydrolysis are as follow.ΔG = –30kJ/molΔH = –20kJ/molΔS = 34kJ/molGlycolysis is an energy-liberating process (ΔG = –218kJ/mol, ΔH = –20 kJ/mol) that is coupled with the conversion of two ADP molecules into two ATP molecules according to the following reaction.Glucose+2ADP+2phosphate→2lactate+2ATP+2H2O What is the value of ΔG (in kJ/mol) for the reaction?    

Consider a 1.00L solution initially containing 0.400 mol ammonia (NH3) and 0.600 mol of ammonium ion (NH4+). What is the pH after addition of 40.0 mL of 0.800M HCl to this solution? (NH4+, Ka = 5.6 × 10–10)?  

Using the table below, answer the following questions about the peptide composed of  the amino acids: Arg-Glu-Ala-Asp.   Use the letters above each structure to answer the following questions: What Amino Acid structure above is the amino acid Arg ? [drop1] What Amino Acid structure above is the amino acid Glu? [drop2] What Amino Acid structure above is the amino acid Ala? [drop3] What Amino Acid structure above is the amino acid Asp? [drop4] Using the pKa values provided, what would be the charge on the peptide at a pH of 6? [drop6] Using the pKa values provided, what is the PI of this peptide? [drop7]

Heat, changes in pH, and changes in salt concentration can cause a protein to denature. Explain how these 3 factors would cause denaturation. Be SPECIFIC in the effects each would cause and on what structures.

With respect to Amino Acid Structure, what do the terms enantiomer, diastereomer and chiral mean? How are they determined?
