What factors dictate whether transamination of amino acids or amino acid biosynthesis occurs under physiological conditions?
Homework Answers
Transamination is a chemical reaction that transfers an amino group to a ketoacid to form new amino acids. This pathway is responsible for the deamination of most amino acids. It is important for the redistribution of amino groups and the production of non-essential amino acids. These reactions occur under physiological conditions as a certain pH is required for these reactions to ionize the amino or carboxyl group of an amino acid which is undergoing transamination. Change of the pH certainly affects the process.

Describe the general role of an a-keto acid in a transamination reaction and the ultimate goal that makes a transamination reaction necessary. So my question is what is the overall goal because I understand that transmination reactions basically transfer a amino group to a alpha ketoacid like oxaloacetate and alpha ketoglutarate. This is done to produce non essential amino acids. But why is this reaction done in the first place if non essential amino acids are produced especially in the...

2. Proteins degradation provides free amino acids, which may be further degraded by deamination and transamination in order to synthesis new compounds, produce energy, or eliminate waste. Provide a brief description for each of the possible fates of free amino acids with specific reference to biochemical reactions and state how the products of these reactions may are utilized. 3. Consider the amount the ATP yield from two different 6-carbon biomolecules: fructose and caproic acid. With specific reference to the catabolic...

Which three statements about amino acids are true? Use this chart of amino acid structures for reference. Lysine has one stereocenter (chiral center). Methionine is a thiol. The Leu side chain does not form hydrogen bonds with other amino acids. The form of glycine used by the human body is D-glycine. Ser and Thr are polar amino acids. Proline has an overall charge at physiological pH (7.4).
