The term hemicellulose describes various sugar (hexoses and pentoses) and uronic acid polymers that, like cellulose, are decomposed by a relatively specialized depolymerization process, followed by a much more rapid assimilation and oxidation of the simple monomer.hexose monomers, specically those sensed by the mitochondria associated HXK, is a subject of major scientic interest (alHabori 1995; Ovadi and Saks 2004). hexoses pdf
Of the hexoses, glucose, fructose, and galactose are physiologically the most important. Glucose is a major mammalian fuel, found widely in fruits and vegetables as a monosaccharide, in disaccharides such as sucrose, maltose, and lactose ( Fig. 184 ), and in polysaccharides such as glycogen and starch (see Chapter 19 ).
molecules, and molecules similar in shape to hexoses), 27 otherligand binding sites and 31 nonbinding sites. The nonbinding sites are surface pockets that look like binding sites but are not known to bind any ligand. The negative dataset is presented in Table 2 Tutorial on How to Name Carbohydrates Carbohydrates: Carbohydrates are known as sugar and composed of monosaccharides, disaccharides, and polysaccharides. Monosaccharides cannot be broken down into simple sugar whereas disaccharides and polysaccharides can be broken into simple sugars. Saccharides mainly consist of carbon, hydrogen, and oxygen. hexoses pdf The pentose phosphate pathway is an alternate route for the oxidation of glucose.
glucose6phosphate 2 NADP CO2 ribose5phosphate 2 NADPH The hexose monophosphate pathway can also be used to synthesize NADPH, while regenerating glucose6phosphate (note that the fructose6phosphate formed in the hexose monophosphate pathway can readily be converted to glucose6phosphate). hexoses pdf Request PDF on ResearchGate Isomerases for biotransformation of Dhexoses Monosaccharides are polyhydroxyl compounds containing several chiral carbons, giving rise to tens of isomeric forms.Rating: 4.54 / Views: 651
