How do the amino acids aspartate and alanine provide a source of carbon for gluconeogenesis? Write out the structures for the interconversions of these amino acids and their corresponding deaminated (amino group removed) α-keto acids.

Expert Solution

These oxaloacetate and pyruvate are used in gluconeogenesis. This is the way by which alanine and aspartate participate in gluconeogenesis by getting converted in pyruvate and oxaloacetate respectively and giving their carbon to form glucose.

Phosphofructokinase is the rate limiting enzyme of gluconeogenesis. Gluconeogenesis is helpful when dietary supply of glucose is not available and the liver glycogen reserves are depleted, Glucose is synthesized from non carbohydrate sources. This is called gluconeogenesis.

The regulation of aspartate derived amino acids in Arabidopsis thaliana is depicted as an integrated network involving pathway end products that act as allosteric effectors on enzymes in intermediate steps. Explain the downstream consequence of a reduction in the amount of S-Adenosyl methionine (SAM) on the overall flux of carbon through the various branches of this metabolic pathway. The first step in converting aspartate into other amino acids is the phosphorylation of aspartate. In A. thaliana, there are five distinct...

Explain how amino acids can be used a source of energy, and outline how ammonia is detoxified.

How many different primary structures could be formed using the four amino acids alanine, phenylalanine, serine...

How many different primary structures could be formed using the four amino acids alanine, phenylalanine, serine and valine? Write the amino acid sequences (using the three letter code) of all the possible peptides that begin with phenylalanine. You must use each amino acid once and only once in each peptide.

Suppose you used a paper chromatography method to separate all the amino acids, but aspartate (aspartic acid) and glutamine were not resolved. Which of the following would be your best next step to separate these 2 amino acids? There may be more than one possibility. Pick one choice and justify it. Choices: (paper electrophoresis at pH 2) (paper electrophoresis at pH 12) (paper chromatography) (trypsin treatment) (paper electrophoresis at either pH).

Bacteria can carry out gluconeogenesis using components of the citric acid cycle or amino acids, but unlike mammals, they can generate glucose from acetate via the glyoxylate pathway. Because bacteria have no organelles, the enzymes of the citric acid cycle and the glyoxylate pathway are not compartmentalized. (a) Why is regulation of the glyoxylate pathway necessary in bacteria? (b) Studies show that bacterial isocitrate lyase is allosterically inhibited by high concentrations of phosphoenolpyruvate. Would you expect to see the inhibition...
