    Determination of Storage (Starch/Glycogen) and Total Saccharides Content in Algae and Cyanobacteria by a Phenol-Sulfuric Acid Method
    苯酚-硫酸法测定藻类和蓝藻中淀粉/糖原的储存和总糖含量

    [Abstract] This is a protocol for quantitative determination of storage and total carbohydrates in algae and cyanobacteria. The protocol is simple, fast and sensitive and it requires only few standard chemicals. Great advantage of this protocol is that both storage and total saccharides can be determined in the cellular pellets that were already used for ...
    Glycogen and Extracellular Glucose Estimation from Cyanobacteria Synechocystis sp. PCC 6803

    [Abstract] Cyanobacteria, which have the extraordinary ability to grow using sunlight and carbon dioxide, are emerging as a green host to produce value-added products. Exploitation of this highly promising host to make products may depend on the ability to modulate the glucose metabolic pathway; it is the key metabolic pathway that generates intermediates ...
    Assaying Glycogen and Trehalose in Yeast
    酵母中糖原和海藻糖的测定

    [Abstract] Organisms store carbohydrates in several forms. In yeast, carbohydrates are stored in glycogen (a multi-branched polysaccharide) and in trehalose (a disaccharide). As in other organisms, the amount of stored carbohydrate varies dramatically with physiological state, and accordingly, an assay of stored carbohydrate can help reveal physiological ...
    Iodine Staining of Escherichia coli Expressing Genes Involved in the Synthesis of Bacterial Glycogen
    参与细菌糖原合成的大肠杆菌表达基因的碘染色
    [Abstract] The presence of intracellular glycogen can be detected by the following iodine staining technique. Cells with glycogen stain dark brown, whereas in its absence they remain with a pale yellowish color. It is hypothesized that iodine atoms fit into helical coils formed by the α-polyglucan to form a coloured glycogen-iodine complex. Here, we have ...

    [Abstract] Glycogen, a soluble multi-branched glucose homopolysaccharide, is composed of chains of α-1,4-linked glucose residues interconnected by α-1,6-linked branches. The classical biosynthetic pathway involves phosphoglucomutase (Pgm), glucose-1-phosphate adenylyltransferase (GlgC or GlgCD), glycogen synthase (GlgA) and branching enzyme (GlgB). ...
    Analysis of Mouse Liver Glycogen Content
    小鼠肝糖原含量检测
    作者:Peichuan Zhang日期:05/20/2012,浏览量:37027,Q&A: 11
    [Abstract] Liver is the major site for glycogen storage. Glycogen content can be significantly altered upon disruption of glucose homeostasis in metabolic syndromes, such as diabetes. Glycogen content can be determined by an acid-hydrolysis method (Passonneau and Lauderdale, 1974). Basically, glucose, the hydrolysis product of glycogen, is converted into ...
