The activity of invertase is negatively correlated with sucrose content and the correlation between phosphorylase activity and sucrose content is positive. Expression of thymidine phosphorylase in cancer 蔗糖酶与蔗糖积累呈负相关,磷酸化酶与蔗糖积累呈正相关。胸苷磷酸化酶在癌组织中表达的研究
Jn the later stage, sucrose synthesis metabolism became the main course with higher activity of phosphorylase leading to sucrose increasing rapidly. 后期磷酸化酶活性高,以蔗糖合成活动为主,蔗糖含量迅速增加。
