The use of pure protein mono- and polymers for human nutrition was studied in a 45-day experiment in which 12 test subjects took part. The first group of 6 persons were given casein (14.8 g nitrogen per day) and the second group--an equivalent mixture made of crystalline L-amino acids. The first group showed no abnormalities in the physiological and biochemical functions. The second group exhibited marked changes in the body: weight losses, negative nitrogen balance, increase of the ammonia concentration in the urine and exhaled air. It appears that amino acid mixtures can be included into the human nutrition only after extensive studies.
在一项为期45天的实验中，对12名受试者使用纯蛋白质单体和聚合物用于人类营养进行了研究。第一组6人给予酪蛋白（每天14.8克氮），第二组给予由结晶L-氨基酸制成的等量混合物。第一组在生理和生化功能方面未出现异常。第二组身体出现明显变化：体重减轻、负氮平衡、尿液和呼出气体中氨浓度增加。看来氨基酸混合物只有在经过广泛研究后才能纳入人类营养。
