	<span style=\"font-size:14px;\">在氧气充足的情况下，葡萄糖可以通过糖酵解和线粒体柠檬酸(TCA)循环为细胞提供能源和碳源。低氧会使TCA循环和电子传递链(ECT)受到抑制，葡萄糖无法被完全氧化，细胞缺乏能源和碳源。为了补充碳源和能源，低氧细胞促进谷氨酰胺代谢途径合成的柠檬酸参与TCA循环，为细胞提供必要的能源和碳源，低氧诱导因子(HIF-1)参与了这一调控。本文主要介绍了低氧环境下的谷氨酰胺代谢，分析了HIF-1与谷氨酰胺代谢之间的相互作用，为低氧糖代谢的调控机制提供理论依据。<br />
When oxygen is sufficient, glucose
can provide energy and carbon source for cells through glycolysis and
mitochondrial citric acid (TCA) cycle. Hypoxia can inhibit TCA cycle and
electron transport chain (ECT), glucose cannot be completely oxidized, and
cells lack energy and carbon sources. In order to supplement carbon source and
energy, hypoxic cells promote glutamine metabolism, synthesize citric acid,
participate in TCA cycle, and provide necessary energy and carbon source for
cells. Hypoxia inducible factor-1 (HIF-1) is involved in this regulation. This
paper mainly introduces glutamine metabolism in hypoxic environment, analyzes
the interaction between HIF-1 and glutamine metabolism, and provides
theoretical basis for the regulation mechanism of hypoxic glucose metabolism.</span>
