The strawberry fruit were sampled from 1 to 8 weeks after full blossom. The contents of sucrose, glucose and fructose and the activities of sucrose phosphate synthase, sucrose synthase, acid invertase, neutral invertase, hexokinase and fructokinase were measured in developing strawberry fruits.

采集花后1~8周的果实，分别测定果实中葡萄糖、果糖、蔗糖的含量和蔗糖磷酸合酶、蔗糖合酶、可溶性酸性转化酶、中性转化酶、己糖激酶及果糖激酶等蔗糖和己糖代谢酶的活性。

Different concentrations of glucose (0.10%, 1.50%, 2.50%, and 4.25%) and LPS (0, 0.1, 1.0, 10.0, 50.0, and 100.0 mg/L) were added into culture media. Then PMCs were incubated in culture medium containing 10.0 mg/L of LPS and 4.25% of glucose for 0, 1, 3, 6, 12, and 24 hours. The hexokinase activity of PMCs was measured with standard glucose-6-phosphate dehydrogenase (G6PDH)-coupled enzymatic assay.

首先将含不同浓度的葡萄糖（0.10%、1.50%、2.50%、4.25%）分别和不同剂量的LPS（0、0.1、1.0、10.0、50.0、100.0mg/L）加入培养基；其次用含4.25%葡萄糖和10.0mg/L LPS的培养基孵育细胞不同时间（0、1、3、6、12、24h）；6-磷酸葡萄糖脱氢酶耦联比色法测定HK活性。

18F-FDG is taken up by cells phosphorylated by hexokinase (whose mitochondrial form is greatly elevated in rapidly-growing malignant tumours) and retained by tissues with high metabolic activity such as most types of malignant tumours.

在被细胞摄取之后，18F-FDG将由己糖激酶（在快速生长型恶性肿瘤之中，线粒体型己糖激酶显著升高）加以磷酸化，并为代谢活跃的组织所滞留，如大多数类型的恶性肿瘤。

The activity of pyruvate formate-lyase and pyruvate dehydrogenase accounts for the observed production of formate, acetate, ethanol and acetoin. In 1978, Hillman isolated one of the mutants of Streptococcus mutans which lack the enzyme activity of dehydrogenase.

当外源性糖丰富的时候，果糖-1，6-二磷酸增加，使LDH活化，90%以上的葡萄糖被转化为乳酸；外源性糖供应不足时，通过丙酮酸甲酸裂解酶和丙酮酸脱氢酶作用产生甲酸、乙酸、3-羟基丁酮和乙醇。
