Relation between the intake of essential amino acids (represented by the phenylalanine intake) and net protein synthesis after a bolus meal with a protein mixture with added carbohydrates in a group of male and females between 45 and 70 years of age in the healthy condition and with disease such as chronic renal failure, COPD and Cancer. All data are expressed per kg fat-free mass (ffm). Between 240 to 330 μmol phenylalanine is present in 1 gram protein. With an average of about 50 kg of ffm/subject, 100 μmol phenylalanine/kg ffm represents about 15 to 20 gram of protein in the bolus drink.
