background:Fructose-bisphosphatase hydrolyzing fructose-2,6-bisphosphate as well as fructose-1,6-bisphosphate (PubMed:19015259). Acts as a negative regulator of glycolysis by lowering intracellular levels of fructose-2,6-bisphosphate in a p53/TP53-dependent manner, resulting in the pentose phosphate pathway (PPP) activation and NADPH production (PubMed:16839880, PubMed:22887998). Contributes to the generation of reduced glutathione to cause a decrease in intracellular reactive oxygen species (ROS) content, correlating with its ability to protect cells from oxidative or metabolic stress-induced cell death (PubMed:16839880, PubMed:19713938, PubMed:23726973, PubMed:22887998, PubMed:23817040). Plays a role in promoting protection against cell death during hypoxia by decreasing mitochondria ROS levels in a HK2-dependent manner through a mechanism that is independent of its fructose-bisphosphatase activity (PubMed:23185017). In response to cardiac damage stress, mediates p53-induced inhibition of myocyte mitophagy through ROS levels reduction and the subsequent inactivation of BNIP3. Reduced mitophagy results in an enhanced apoptotic myocyte cell death, and exacerbates cardiac damage (By similarity). Plays a role in adult intestinal regeneration; contributes to the growth, proliferation and survival of intestinal crypts following tissue ablation (PubMed:23726973). Plays a neuroprotective role against ischemic brain damage by enhancing PPP flux and preserving mitochondria functions (By similarity). Protects glioma cells from hypoxia- and ROS-induced cell death by inhibiting glycolysis and activating mitochondrial energy metabolism and oxygen consumption in a TKTL1-dependent and p53/TP53-independent manner (PubMed:22887998). Plays a role in cancer cell survival by promoting DNA repair through activating PPP flux in a CDK5-ATM-dependent signaling pathway during hypoxia and/or genome stress-induced DNA damage responses (PubMed:25928429). Involved in intestinal tumor progression (PubMed:23726973).

文献和实验C6 H12 O6 。 D-果糖，亦称左旋糖，是代表性的己酮糖之一，在果汁、蜂蜜中呈游离状态存在，为蔗糖的成分。苹果、番茄中含量特别多，菊科植物含有大量像菊根粉（ inulin）那样的果聚糖。天然游离的果糖是吡喃型，但寡糖、多糖中往往以呋喃型的形态存在。蔗糖受转化酶（蔗糖酶）的作用可游离出果糖。另外甘露醇和山梨醇在相应的脱氢酶作用能氧化成果糖。与甲基吲哚和盐酸一起加温可出现紫红色。为醣类中甜味最强的糖，但α型的甜味仅及β型的三分
最常见的六碳酮糖，存在于果汁、花蜜、蜂蜜及动物精液中。天然的果糖均为 D构型。游离的 D-果糖以吡喃型为主，寡糖和果聚糖中处于结合状态的果糖，则以呋喃型和其他糖联接，如：蔗糖及菊科植物根中的菊粉，均含有结合的呋喃型果糖。在一定的条件下，可自水溶液得到果糖的晶体，果糖晶体熔点为 102～ 104℃，比旋 -132.2°，变旋达平衡时为 -92.2°。 果糖可以被还原为糖醇，也可以被氧化为糖酸。果糖还具有一些醛糖所没有的性质，如：与间苯二酚的呈色反应等。在生物体内，果糖

糖酵解的中间产物，称为哈杨二氏酯（Harden－Young ester）。A.Handen和W.J.Young（1906）发现，在酵母的酒精发酵中需要磷酸盐，并证明磷酸盐是以1，6－二磷酸果糖的形态被摄入而进行发酵的。在醣酵解时，它是由磷酸果糖激酶作用于6-磷酸果糖而形成的。通过醛缩酶的作用可以分解成磷酸二羟丙酮和3－磷酸甘油醛。
