Starch solution molecular weight

WebbIt is calculated using the molecular weight of the starch monomers (162.14 g/mol) and is referred to as total starch. To determine the real starch concentration, ... The recovery of pure starch control solutions should be within 100 ± 5 % and for extracted starch samples within 100 ± 10 %. 6. Performance data 6.1. WebbBackground: The development of hydroxyethyl starches (HES) with low impact on blood coagulation but higher volume effect compared with the currently used HES solutions is of clinical interest. We hypothesized that high molecular weight, low-substituted HES might possess these properties. Methods: Thirty pigs were infused with three different HES …

Molecular weight analysis of starches: Which technique?

WebbStarch is a mixture of two polymers: amylose and amylopectin. Natural starches consist of about 10%–30% amylase and 70%–90% amylopectin. Amylose is a linear polysaccharide composed entirely of D-glucose units joined by the α-1,4-glycosidic linkages we saw in maltose (part (a) of Figure 5.1.1). Experimental evidence indicates that amylose ... WebbColloidal solution volume expander that contains hydroxyethyl starch 130/0.4. 130 refers to the molecular weight (130,000 daltons) 0.4 refers to the low molar substitution by hydroxyethyl groups.
