Glyceraldehyde 3-phosphate

甘油醛-3-磷酸

Glyceraldehyde 3-phosphate or G3P is the product of the Calvin cycle. It is a 3-carbon sugar that is the starting point for the synthesis of other carbohydrates.

甘油醛-3-磷酸（G3P）是卡尔文循环的产物。它是一种三碳糖，是其他碳水化合物合成的起始物质。
Some of this G3P is used to regenerate the RuBP to continue the cycle, but some is available for molecular synthesis and is used to make fructose diphosphate. The fructose diphosphate is then used to make glucose, sucrose, starch and other carbohydrates on the anabolic side of metabolism. On the catabolic side, G3P is also involved in one step of glycolysis on the way to producing pyruvate.

部分G3P被用来再生RuBP以继续循环，但另一部分则可用于分子合成，用于生成果糖二磷酸。果糖二磷酸随后被用来合成葡萄糖、蔗糖、淀粉和其他碳水化合物，这些过程发生在代谢的合成侧。在代谢的分解侧，G3P也参与了糖酵解的一个步骤，该步骤有助于生成丙酮酸。
