Chemically, starch can be defined as a polysaccharide composed of α-D-glucopyranosyl units that can be linked in either α-D-(1–4) and/or α-D-(1–6) linkages. These molecular linkages form to types of molecules: the linear amylose formed by approximately 1000 glucose units linked in ...
Carbohydrates are the main energy source of our diet. A large part of these carbohydrates are absorbed as glucose in the small intestine whereas 'indigestible' oligosaccharides, resistant starch and more generally dietary fibres are available for bacterial fermentation. Intrinsic characteristics of carbohyd...
Furthermore, Se-polysaccharides isolated from Se-enriched Chrysanthemum morifolium markedly reduce postprandial blood glucose and remit the typical symptoms such as polydipsia and polyphagia in diabetic mice [15, 16]. It is of theoretical and applied significance to investigate chemical structure, ...
The amide III band (1200–1300 cm− 1), which includes the NH bend and the CN stretch modes, can also provide information about the structure of proteins. Sign in to download full-size image Fig. 2. FT-Raman spectra of wheat starch and wheat flour, showing the protein content ...

The chemical structure of torrefaction tar possesses an analytical challenge to study. This is due to the presence of complex mixtures containing compounds of low and high polarity which are tendentious to resolve with conventional techniques [5]. During torrefaction, three different product groups are...
