Biochemistry Question
In hypoglycemia, the liver is not utilizing glucose as an energy
source while the rest of the body continues to use glycolysis to
generate ATP. Explain in detail why this happens. Also, why is the
liver not using glucose?

You will investigate how unnatural amino acid mutagenesis works. Take time to examine what changes needed to be made to the tRNA to allow for an unnatural amino acid to be used instead of the native substrate. Also focus on what codons are used to recognize the modified tRNA. How many different codons are there that can be used? What are they called?

2. The common naturally occurring form of cysteine has
a chirality center that is named (R), however;
(a) What is the relationship between (R)-cysteine and
(S)-alanine?
(b) Do they have the opposite three-dimensional configuration (as
the names might suggest) or the same configuration?
(c) Is (R)-cysteine a D-amino acid or an L-amino acid?

Consider a 0.487 L solution of the amino aspartic acid (0.685 M), which ahs a carboxylic acid group (pKa = 2.10), an amine group (pKa = 9.82), and a carboxylic acid side chain (pKa = 3.86). How many liters of 2.59 M NaOH would you need to add to reach the isoelectric point of the amino acid?
