We studied the metabolic kinetics after short-time infusion of a 10% standardised L-amino-acid-mixture in 19 healthy adults. The following results were of special interest: 1. Nearly all amino-acids had half life times between 7 and 10 minutes. 2. The male adults showed averagely higher clearance and transfer rates in contrast to female. There was a statistical difference for serine and alanine in the transfer rates, for serine, methionine and glycine in the clearance. 3. The maximum of daily turnover could be calculated for about 5,6 g/kg body weight. Based on the measured transfer rates we discuss the composition of some standardised L-amino-acid-mixtures.
