Amino Acids Part 1 Flashcards
Synthesis of biological compounds
anabolism
breakdown of compounds
catabolism
what is the main source of amino acids
dietary protein
is there a dedicated storage form of amino acids?
no
where do mammals acquire most of their energy?
carbs, fats, and proteins
does carb breakdown efficient? how much energy is yielded?
carb breakdown is the most efficient but lowest amount of energy
what amount of energy does protein release?
intermediate amount of energy, however nitorgen containing by product must be eliminated
what is the function of the liver with amino acids?
- Synthesizes non-essential amino acids
- removes & breaks down excess amino acids
- removes ammonia from the blood & converts it to urea
- makes other nitrogen-containing compounds
What locations does amino acids feed in to
Several locations such as pyruvate, acetyl CoA, and TCA intermediates
What can amino acids be converted to?
Pyruvate and glucose. fatty acids cannot!
What is the first step in converting amino acids into glucose or other intermediates?
Deamination
What is the most common mechanism for deamination
Transamination
What does transamination do?
Exchanges the amino group with the keto group on an alpha-keto glutarate resulting in glutamic acid
What is the key intermediate in amino acid metabolism
Glutamate
Glutamate can be deaminate to give..what?
free ammonia
