补救合成途径

因为在绝大多数的动物体内，核苷酸的合成原料并不依赖消化道的吸收来提供，而是以氨基酸及其代谢产物为主要原料的从头合成和补救合成途径来满足机体的需要。

In most animals , the materials needed by nucleotide synthesis are not absorbed from digestive systems , but from amino acids and their metabolizing products through two pathways named as de novo synthesis pathway and salvage synthesis pathway .

APRT编码基因在体细胞胚发育过程中的活跃表达，意味着在高等植物胚胎发生或发育过程中存在核苷酸补救合成途径。

APRT coding gene was active during the development of somatic embryogenesis , this indicated a way of nucleotide remedial synthesis existed during embryogenesis or embryo development in higher plant .
