Mathematical Show that, for a pure weak acid in water, pH 5 (pKa 2 log [HA])/2.
Answer to relevant QuestionsBiochemical connections Suggest a suitable buffer range for each of the following substances: (a) Lactic acid (pKa 5 3.86) and its sodium salt (b) Acetic acid (pKa 5 4.76) and its sodium salt (c) TRIS (pKa 5 8.3; see Table ...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. Consider the following peptides: Phe! Glu! Ser! Met and Val! Trp! Cys! Leu. Do these peptides have differ-ent net charges at pH 1? At pH 7? Indicate the charges at both pH values. MatheMatical Predict the predominant ionized forms of the following amino acids at pH 7: glutamic acid, leucine, threonine, histidine, and arginine. What is the highest level of protein structure found in collagen?
