摘　　要：本文报道了南京城区90份不同哺乳期(1～42天)母乳中游离氨基酸含量。结果表明:人乳申第一丰富的游离氨基酸是谷氨酸,其次是牛磺酸。人乳中的必需游离氨基酸在初乳中合量最高,以后随泌乳时间的延长而下降。文中讨论了人乳游离氨基酸在婴儿早期喂养中的作用。本研究为提倡母乳喂养和配制人乳化的婴儿食品提供了科学依据。Free amino acids were analysed in 90 human milk samples during the first 6 weeks of lactation in Nanjin city. Glutatnic acid was the most and taurine was the second abundant component of the free amino acids in human milk. The free essential amino acids were highest in colostral milk and declined with advancing lactation. The possible roles of free amino acids in human milk for feeding infant in the first stage was discussed. The results of this study support that breast milk is beneficial for infants and suggest that the formulas should be supplemented with taurine.
