a) Name the following (with full names): (a) The amino acid
without a primary amino group
(b) An amino acid that could form a salt bridge with an Asp
residue in a protein interior:
(c) The amino acid that contains sulfur that doesn’t make
disulfide bonds:
(d) Name one of the three amino acids that have hydroxylated R

e) Draw the structure of the tetrapeptide SKYP at a pH of 5,
making sure you include the structures of...
List the sequence of structures that a single amino acid
(initially in a protein molecule that you eat) goes through from
the moment it passes your lips to when it ends up in a hepatocyte.
Then explain what (if any) chemicals relevant to digestive
physiology it is exposed to at each step and what happens to the
protein and eventually protein fragments each step of the way.
Using names and structures show the transformation of pyruvic
acid to ethyl alcohol. At the arrows between each step give the
names of the enzyme and coenzyme involved.
The amino acid glutamic acid has the molecular formula C5H9NO4,
and the amino acid isoleucine has the molecular formula C6H13NO2.
Determine how many moles of isoleucine contain the same number of
atoms as 1.96 mol of glutamic acid.

2.A type of chromatography that fractionates proteins based on
differences in their size is ____________________________________
chromatography.

In Anfinsen's experiments on the structure and function of
RNase, he found that non-covalent bonds were key in determining the
_________________________ structure of the enzyme.
