Question: Which would you think would be a stronger interaction and
Which would you think would be a stronger interaction and why: an interaction between a sodium ion and the partial negative charge on the oxygen in ethanol (CH3CH2OH), or the interaction between two ethanol molecules?
Answer to relevant QuestionsMatheMatical 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. If you were to have a mythical amino acid based on glutamic acid, but one in which the hydrogen that is attached to the g-carbon were replaced by another amino group, what would be the predominant form of this amino acid at ...Identify the polar amino acids, the aromatic amino acids, and the sulfur-containing amino acids, given a peptide with the following amino acid sequence: Val! Met! Ser! Ile! Phe! Arg! Cys! Tyr! Leu You hear the comment that the difference between wool and silk is the difference between helical and pleated- sheet structures. Do you consider this a valid point of view? Why or why not? In oxygenated hemoglobin, pKa 5 6.6 for the histidines at position 146 on the b-chain. In deoxygenated hemoglobin, the pKa of these residues is 8.2. How can this piece of information be correlated with the Bohr effect?
