| 摘 要： | １９９３年分析了不同大小斑节对虾肌肉中游离氨基酸含量和肌肉蛋白质 的氨基酸组成。虾体肌肉中有各种游离氨基酸存在，但数量很少，而且比例与肌肉 中结合氨基酸不一致。不同大小斑节对虾，其肌肉中氨基酸组成基本一样，不同的 是小虾的半胱氨酸、蛋氨酸含量比中虾、成虾的低；成虾的缬氨酸、异亮氨酸含量比 小虾、中虾的低，而酪氨酸、苯丙氨酸、天门冬氨酸较高。随着虾体的长大，甘氨酸、 丙氨酸的含量逐渐下降，而脯氨酸的含量升高。雌雄虾的氨基酸组成基本一致，只 是雄虾的甘氨酸含量偏低，精氨酸含量偏高。

| Abstract: | This paper analyzed the free amino acid content and amino acid profile of muscle tissue of shrimp P. monodon, at different size. Many kind of free amino acids existed in muscle tissue of shrimp with little amount, and its ratio was not consistent with amino acid that in peptide bound. The amino acid profile of muscle tissue of shrimp, which from juvenile to adult, did not differ significantly for most of the amino acids. The juveniles of shrimp had significantly higher cystine, methionine'than the middle and adult size. The adult shrimp had significantly higher tyrosine, phenylalanine and asparagine content but lower valine and isoleucine levels compared to juvenile and middle shrimp. Alog with the shrimp growth, the level of glycine and alanine was lower and lower, but proline content was higher and higher. The amino acid profile of muscle tissue of male and female shrimp did not differ significantly for most of the amino acids, however, the male had significantly higher arginine content but lower glycine level compared to the female. |
