Amino Acid Metabolic Pool Flashcards
1
Q
What is the amino acid metabolic pool
A
It is the blood composition of amino acids at any given time due to the combined efforts of these 3 sources of amino acids
- taken up by tissue cells
- turnover of tissue protein
- synthesis of non essential amino acids
2
Q
A cell is said to be in DYNAMIC EQUILIBRIUM___
A
If it takes up as much amino acids as it loses
NB - if loss is greater than uptake, cell is said to “waste”
If uptake is greater the cell grows
3
Q
Define protein turnover
A
It is the overall process accounting for the metabolic pool where proteins of the human body are constantly degraded and re-synthesized
4
Q
Proteins with regions rich in __ have shorter life spans
A
PEST - proline, glutamate, serine, threonine
