PLP is a cofactor for a number of enzymes involved in amino acid metabolism. Give an example of reaction in which PLP participates in cleavage of the a, b, and c bonds of an amino acid, as diagrammed in shown Fig.

Which of the following branched chain amino acids form Succinyl CoA when catabolized? (more than one aswer) a. Valine b. Leucine c. Isoleucine

What is the normal fate of citrate formed by the condensation of acetyl CoA with oxaloacetate?

How many -amino acids participate directly in the ureacycle? Of these, how many can be used for protein synthesis?

Amino transferases catalyze the transfer of amino groups to alpha-keto acids with pyridoxal phosphate as the prosthetic group. Pyridoxal phosphate can accept an amino group, and its aminated form, pyridoxamine phosphate, can donate its amino group to an alpha-keto acid. Draw the detailed mechanism of the transamination reaction in the active site of an aminotransferase.  Use the glutamate oxaloacetate transaminase as an example.

Explain the relationship between a-ketoglutarate, glutamate, and glutamine in amino acid anabolism?

which of the following compounds can serve as a precursor for gluconeogenesis. A) acetate  B)acetoacetate C) alanine D)  leucine E) palmitate
