Abstract: 
The biological value (BV) of an amino acid mixture, according to the potato-egg principle (KE), was determined in a long-term metabolic balance test using oral and parenteral intake in 3 healthy adults. The following values were determined: KE-amino acid pattern with oral intake, BV = 134.4; KE-amino acid pattern with parenteral intake, BV = 131.4; egg protein (reference) with oral intake, BV = 100. In humans the long-term metabolic balance experiment with compensated N balances was used to test N substances like whole egg protein and amino acids (under parenteral and oral intake); the BV of a N substance was defined as the reciprocal value of the minimum N requirements compared with the reference protein whole egg, which was set at 100. The results confirmed the almost identical utilization and value of N substances (amino acids), even with different methods of intake (oral and parenteral nutrition), and the ability to reproduce the BV of the optimal potato-egg protein mixture (65% potato N + 35% egg N with oral intake: BV = 137.6) by means of simulation through corresponding L-amino acids, considering the modification necessary for technical and physiological reasons, which concerned the non-essential part of the pattern.
