Webbeta-glycosidic Dietary fiber is NOT: digested or absorbed by the human intestine Which of the following is an FDA-approved health claim for fiber? "Diets high in whole-grain foods and other plant foods and low in total fat, saturated fat, and cholesterol may help reduce the risk of heart disease and certain cancers."
WebGlycosidic bonds (also called glycosidic linkages) can be of the alpha or the beta type. An alpha bond is formed when the OH group on the carbon-1 of the first glucose is below the ring plane, and a beta bond is formed when the OH group on the carbon-1 is above the ring plane.
