山梨醇，一种细菌培养补充剂，已经用于制备选择性平板培养基以培养山梨醇发酵细菌，包括大肠杆菌和小肠结肠炎耶尔森菌的菌株。它也被用作制备免疫电镜用果蝇胚胎的成分之一。它还被用作葡萄糖醛酸木聚糖的添加剂，作为潜在的食品包装材料。
Biochem/physiol Actions
山梨醇是一种糖醇，通常用作糖的替代品。它自然产生，也是由葡萄糖合成产生的。食品工业使用山梨醇作为甜味剂、保湿剂、乳化剂、增稠剂或膳食补充剂形式的添加剂。在化妆品、纸张和药品中也发现了山梨醇。自然地，山梨醇通过光合作用广泛存在于植物中，从藻类到蔷薇科的高阶果实。
山梨醇是一种缓慢代谢的糖醇，由葡萄糖还原产生。在多元醇通路中，山梨醇被山梨醇脱氢酶进一步氧化成果糖。山梨醇不容易扩散到细胞膜上，可能会对细胞造成渗透损伤。山梨醇的代谢在糖尿病相关血管并发症的病理学中是最重要的。

Diabetes-specific microvascular disease is a leading cause of blindness, renal failure and nerve damage, and diabetes-accelerated atherosclerosis leads to increased risk of myocardial infarction, stroke and limb amputation. Four main molecular mechanisms have been implicated in glucose-mediated vascular damage. All

A pathway from glucose via sorbitol bypasses the control points of hexokinase and phosphofructokinase in glucose metabolism. It also may produce glycerol, linking the bypass to lipid synthesis. Utilization of this bypass is favored by a plentiful supply of glucose--hence

Free films based on glucuronoxylan isolated from aspen wood were prepared by casting from aqueous solutions and drying in a controlled environment. Addition of xylitol or sorbitol facilitated film formation and thus examination of the material properties of these films.
