Parameter values used in nitrogen metabolism model

Parameter Name	Value	References
Blood Volume	6.59 La
Average Liver Mass	1561 g	[32]
Average Human Mass, Male	88.7 kg	[1]
Time Through Sinusoid	4.3 s	[33]
Initial Urea	5.5 mM
Initial Ammonia	0 μM
Initial Glutamine	0 mM
Recommended Daily Protein	71 g	[34]

^aBlood volume is about 5.2 L for a 70 kg individual [35]. The value used above was determined by assuming a linear relationship of blood volume with body mass for an individual weighing 88.7 kg. This is the volume of the blood compartment used to calculate metabolite concentrations
