Question
Chapter 18.4, Problem 36PP
(a)
Interpretation Introduction
Interpretation:
The tyrosine amino acid needs to be classified as non-polar or polar. If it is polar then the R group needs to be classified as neutral, acidic or basic. Also, if it is hydrophobic or hydrophilic needs to be identified.
Concept Introduction :
The amino acid consists of two
(b)
Interpretation Introduction
Interpretation:
The leucine amino acid needs to be classified as non-polar or polar. If it is polar then the R group needs to be classified as neutral, acidic or basic. Also, if it is hydrophobic or hydrophilic needs to be identified.
Concept Introduction :
The amino acid consists of two functional groups that is amino group as well as carboxylic acid group. There are 20 essential amino acids which are different from each other due to the different R group attached to the carbon containing amino as well as carboxyl groups.
(c)
Interpretation Introduction
Interpretation:
The methionine amino acid needs to be classified as non-polar or polar. If it is polar then the R group needs to be classified as neutral, acidic or basic. Also, if it is hydrophobic or hydrophilic needs to be identified.
Concept Introduction :

A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
