The sizes of amino acid pools in growing Xenopus laevis oocytes have been measured. The total free amino acid content per oocyte increases nearly 25-fold during oocyte growth. Together, glutamic acid and aspartic acid account for approximately 59-75% of the total amino acid pool in Xenopus oocytes. On the other hand, methionine and cysteine are the least abundant of the amino acids detected, each accounting for less than 0.7% of the total pool in developing oocytes. It is argued that the acid-extractable amino acid pool represents the precursor pool used in protein synthesis.
已对非洲爪蟾生长中的卵母细胞中氨基酸库的大小进行了测量。每个卵母细胞的总游离氨基酸含量在卵母细胞生长过程中增加了近25倍。谷氨酸和天冬氨酸共同约占非洲爪蟾卵母细胞总氨基酸库的59 - 75%。另一方面，甲硫氨酸和半胱氨酸是检测到的氨基酸中含量最少的，在发育中的卵母细胞中，每种氨基酸占总库的比例均不到0.7%。有人认为，酸可提取氨基酸库代表了蛋白质合成中使用的前体库。
