[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 ...

[Abstract] Inorganic polyphosphate (polyP) is a linear polymer present in both prokaryotic and eukaryotic organisms and made from three to hundreds of orthophosphate residues linked by phosphoanhydride bonds. The biological role of this molecule goes beyond serving as Pi store or energy source to replace ATP. ...

[Abstract] The EmulsiFlex-C3 homogenizer is powered by an electric motor. The pump does not require a compressor for it to run. This equipment can be used to disrupt cells at a large scale. The EmulsiFlex-C3 has a fixed flow-through capacity of 3 L/h. It has the ability to process samples as small as 10 ml. The ...
