Starch types

Among other polysaccharides studied were those elaborated by Neisseria per-flava (starch-type polysaccharide), Polytomella coeca (a starch richer in amy-lopectin than most natural starches), Pseudomonas morsprunorum (Wormald) (levan), Acetobacter acetigenum (cellulose), Aerobacter aerogenes (NCTC 8172) (Klebsiella Type 164), Bacillus megaterium. Bacterium pruni, and Bacterium prunicola (polyfructoses of the levan type).

Most native starch types are slightly phosphorylated with phosphate groups monoesterified to the glucose residues (Blennow et ak, 2002). The presence of phosphate esters in starch has been known for more than a century (Fembach, 1904). The content of phosphate esters in starch...

Cationization of waxy maize, corn and barley starches in aqueous alcohol slurries is most effective at 35-65% ethanol for all starch types a 1 1 starch to water ratio gave highest DS values.51 A process for making cationic or amphoteric starches in aqueous, alkaline alcoholic solvents has also been described.52...

The most abundant carbohydrate ingested by humans is of the starch type— amylose and amylopectin (about 200 g/day). Smaller quantities of carbohydrate enter the digestive tract in the form of lactose (about 7 g) and sucrose (about 20 g see Chapter 9 for structures). All dietary carbohydrates must be digested to monosaccharides to be absorbed.

A second stage occurs at 90°C when amylopectin-rich granules swell and deform (Hermansson and Svegmark, 1996). These temperatures are altered by starch type, and the presence of small solutes sugars elevate the gelatinisation temperature and ionic solutes exhibit varying effects related to their position in the Hoffmeister series. 

Glycogen shows the characteristic infrared absorption spectrum of starch-type polysaccharides.—The infrared spectrum of glycogen, in the frequency range 730-960 cm., has three absorption peaks, at 928 3, 838 3, and 760 2 cm.- the absorption peak at 838 cm.- is displayed by all carbohydrates containing a-D-glucopyranose units, whilst the peaks...
