1.研究了将D2 O掺入孵育培养基中对禁食大鼠肝细胞糖酵解和糖原合成的影响。2.重水,D2 O,在浓度从10%到40%的替代,刺激葡萄糖摄取,乳酸生产和CO2产量从葡萄糖。在10 mM葡萄糖下,40%D2O使葡萄糖摄取增加一倍,使CO2产量增加40%,并使乳酸产量增加350%。3.乳酸产生的刺激在较高的葡萄糖浓度下降低,但即使在80 mM葡萄糖下仍然很大。4.在30 mM葡萄糖浓度以上,对CO2产生没有影响。10%D_2O对乳酸摄取、乳酸氧化和乳酸代谢的抑制作用不明显。在40%D2O下,抑制范围为10%至20%。6. D2 O对葡萄糖激酶或葡萄糖-6-磷酸酶的速率没有影响。7. D_2O对果糖、2,6-P含量无明显影响。
1. The effect of incorporating D2O into the incubation medium on glycolysis and gluconeogenesis by hepatocytes from fasted rats was examined. 2. The substitution by heavy water, D2O, at concentrations from 10 to 40%, stimulated glucose uptake, lactate production and CO2 yields from glucose. At 10 mM glucose, 40% D2O doubled glucose uptake, increased CO2 production by 40%, and increased lactate production by 350%. 3. The stimulation of lactate production decreased at higher glucose concentrations, but was still substantial even at 80 mM glucose. 4. There was no effect on CO2 production above glucose concentrations of 30 mM. 5. Ten percent D2O showed little inhibition of lactate uptake, its oxidation and gluconeogenesis. At 40% D2O the inhibition ranged from 10 to 20%. 6. No effect of D2O on the rate of glucokinase or glucose-6-phosphatase was observed. 7. The concentration of fructose, 2, 6-P was not affected by D2O.
