WRT intake and excretion, what is 'N balance' or 'equilibrium'? Is it normal in an adult?
|
Intake = Excretion
Normal state in an adult (NB Not a child, who is growing) |
|
|
WRT intake in excretion, what is a positive N balance? Is it normal in an adult? What is it indicative of?
|
Intake > Excretion
Normal state in growth, pregnancy and recovery from loss |
|
|
WRT intake and excretion, what is a negative N balance? Is it normal in an adult? What is it indicative of?
|
Intake < Excretion
Never normal (In adult or child), indicates illness, trauma or inadequate protein intake |
|
|
In a non-growing adult, excretion of nitrogenous compounds equals intake of nitrogenous compounds T/F
|
T
|
|
|
Must understand that with intake of protein above requirements, N balance is maintained maintained
|
Except after a period of negative N balance, where lost tissue protein needs to be restoerd
|
|
|
What is the average requirement of protein intake per day?
|
0.66g/kg body weight
|
|
|
What is the safe and adequate intake of protein per day?
|
0.83g/kg body weight
|
|
|
What is the safe and adequate intake of protein, asa percentage, and what is the average UK intake?
|
8% safe and adequate intake, 15% is the average (1.2g/kg body weight)
|
|
|
How many essential amino acids are there?
|
9
|
|
|
Essential amino acids are those which can be synthesised by the body T/F
|
False! They cannot be synthesised by the body (there are 9 of them which must be provided by the diet)

What are the 9 essential amino acids?
PVT TIM H(A)LL |
Phenylaline
Valine Tryptophan Threonine Isoleucine Methionine Histidine A Leucine Lysine |
|
|
What are the three 'trul dispensable' amino acids that are synthesised directly from common metabolic intermediates?
|
Alanine (from pyruvate)
Glutamate (from alpha-ketoglutarate) Asparate (from oxaloacetate) |
|
|
From what common metabolic intermediate is alanine synthesised from?
|
Pyruvate
|
|
|
From what common metabolic intermediate is glutamate synthesised from?
|
Alpha-ketoglutarate
|
|
|
From what common metabolic intermediate is asparate synthesised from?
|
Oxaloacetate
|
|
|
Mucous is rich in cysteine and threonine, which is one of the uses of protein in the body T/F
|
T
|
|
|
Its primary functions are to increase blood sugar through gluconeogenesis; suppress the immune system; and aid in fat, protein and carbohydrate metabolism
|
Cortisol
