A possibility and some peculiarities of phosphatase degradation of sedoheptulose-1,7-diphosphate in the myocardium has been demonstrated. The reaction products are inorganic phosphate and sedoheptulose-7-phosphate; the latter product is the substrate of the transketolase reaction during pentose phosphates production. The process is largely localized in the soluble fraction of heart cells; in cellular organelles it is represented in a lesser degree. Possible regulatory mechanisms of pentose phosphate biosynthesis in animal tissues are discussed.
已证实心肌中磷酸己糖-1,7-二磷酸磷酸酶降解的可能性及一些特性。反应产物是无机磷酸盐和磷酸己糖-7-磷酸；后一种产物是戊糖磷酸生成过程中转酮醇酶反应的底物。该过程主要定位于心脏细胞的可溶部分；在细胞器中程度较低。讨论了动物组织中戊糖磷酸生物合成可能的调节机制。
