二羟丙酮（DHA）是一种重要的化工原料，在精细化工、制药、食品等方面具有广泛的应用前景。

Dihydroxyacetone is a kind of important chemical materials , which has been widely applied in chemistry , pharmacy , food and so on .

高渗胁迫条件下盐藻细胞内甘油的含量迅速增加，3-磷酸甘油磷酸酶（GPase）的活性和二羟丙酮还原酶（DHA-RD）催化二羟丙酮转化为甘油的活性明显提高。

The intracellular glycerol content accumulated and activities of glycerol 3-phosphate phosphatase and dihydroxyacetone reductase catalyzing dihydroxyacetone to glycerol were enhanced in response to hyperosmotic stress .

从节点磷酸二羟丙酮和三磷酸甘油醛流向三磷酸甘油合成甘油的碳流量增加了67.2%，而流向三梭酸（TCA）循环的流量减少了26.9%。

At the same time , the carbon flux flowed toward glycerol-3-phosphate ( G3P ) to form glycerol from dihydroxyacetone phosphate ( DHAP ) and glyceraldehydes-3-phosphate ( GAP ) node increases 67.2 % , while the carbon flux flowed toward TCA cycle decreases 26.9 % .
