일반 설명
Dextran is an exopolysaccharide synthesized by lactic acid bacteria from sucrose. It consists of repeating units of D-glucose with the monomers joined to each other through α-1,6 linkages. In addition, the linear D-glucose chains show branching at frequent intervals, linked by α-1,4, α-1,3, or α-1,2 linkages.
애플리케이션
The analytical standards can also be used as follows:
- High-performance size exclusion chromatography (HPSEC) based determination of the molecular weight of a dextran synthesized by Leuconostoc citreum B-2, isolated from a fermentation product of pineapple
- Determination of molecular weight of polysaccharides obtained from four Auricularia species by high-performance liquid chromatography using a water-soluble gel column
- Identification of molecular weight of a water-soluble polysaccharide isolated by anion exchange chromatography from the dried leaves of C. paliurus by gel permeation chromatography (GPC)
- Gel permeation chromatography (GPC) based molecular weight measurement of a dextran produced by two strains of Leuconostoc mesenteroides
- Estimation of molecular weight of a water-soluble polysaccharide obtained from thinned-young apple by high-performance size exclusion chromatography (HPSEC)
