生化机理 | Gluconolactone is a product of the oxidation of glucose by glucose oxidase. It has been found to be a mixed type, noncompetitive inhibitor for the hydrolysis of p-nitrophenyl alpha-D-glucoside by glucoamylase, an enzyme that breaks down starch into glucose. |
一般描述
可溶于水,并自动均匀地水解成葡萄糖酸。醌蛋白葡萄糖脱氢酶将D-葡萄糖转化成GDL,这逐渐降低了pH值并转录控制灵菌红素的生产。 GDL常用于食品工业,通过酸化使酪蛋白酸钠凝胶化。 GDL有助于克服使用起始细菌培养物的困难和变化。
已用于制备冷固化凝胶、和水凝胶。
