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)

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
