F. CALCULATIONS

1. Tryptophan Concentration in Samples:

TRP (g/100g sample) = (CTS – CTB) x (volume / SW) x (100g/1000mg/g) Where:

CTS = Concentration of Tryptophan in Sample (mg/L) CTB = Concentration of Tryptophan in Blank (mg/L) Volume = Final volume in Liters i.e. 50 mL = 0.05L SW = Sample Weight in grams
