MatheMatical Sketch a titration curve for the amino acid cysteine, and indicate the pKa values for all titratable groups. Also indicate the pH at which this amino acid has no net charge.
Answer to relevant QuestionsMatheMatical Sketch a titration curve for the amino acid lysine, and indicate the pKa values for all titratable groups. Also indicate the pH at which the amino acid has no net charge. Identify the charged groups in the peptide shown in Question 4 at pH 1 and at pH 7. What is the net charge of this peptide at these two pH values? What are the structural differences between the peptide hormones oxytocin and vasopressin? Woolen clothing shrinks when washed in hot water, but items made of silk do not. Suggest a reason, based on information from this chapter. You are studying with a friend who is describing the Bohr effect. She tells you that in the lungs, hemoglobin binds oxygen and releases hydrogen ion; as a result, the pH increases. She goes on to say that in actively ...
