说明

D-果糖（水果糖）是一种还原糖。在水果中，它是一种非常重要的糖成分，主要以游离形式存在于植物中，通常与蔗糖和D-葡萄糖一起存在。它是菊粉多糖的成分，也是二糖、三糖和寡糖的成分。

D-果糖是一种重要的单糖，用途广泛。D-果糖用于碳水化合物研究、有机和生物有机合成；作为模型化合物；作为参考物质、作为酶底物和作为营养培养基。它可以通过与葡萄糖分离和蔗糖水解（转化）产生。1它还具有代谢和内分泌影响，这表明果糖的摄入增加是肥胖和胰岛素抵抗综合征中观察到的伴随代谢异常的一个促成因素。

一般描述

D-Fructose (fruit sugar) is a reducing sugar. In fruits it is a very important sugar component, and mostly exists in free form in plants and often together with sucrose and D-glucose. It is a component of polysaccharide inulin and also a component of di-, tri- and oligo-saccharides.[1][2][3]

生化/生理作用

D-Fructose is an important monosaccharide used in a wide range of applications. D-fructose is used in carbohydrate research, in organic and bioorganic synthesis; as a model compound; as a reference material, as an enzyme substrate and as a nutrient medium.[1][2][3]

It can be produced by separation from glucose and by hydrolysis (inversion) of sucrose.1 It also possess metabolic and endocrine impact that shows that increased consumption of fructose is a contributing factor in the development of obesity and the accompanying metabolic abnormalities observed in the insulin resistance syndrome.[1][2][3]
